Based on this demand, there needs to be enough space inside the electronic device to accommodate the components, which will occupy the space of the electronic device and invisibly increase the size of the electronic device.

[0004] For smaller wearable devices, how to install components that can integrate multiple functions to improve user experience without significantly increasing the size of the device is an urgent problem that needs to be solved. Summary of the Invention

[0005] An embodiment of the present application provides a wearable device, which includes a housing and an input device mounted on the housing through a mounting hole in the housing. The input device includes a connected stem and a head. Components related to fingerprint recognition are mounted within the input device. For example, a PPG sensor is mounted in the stem or the head. For another example, a PPG sensor is mounted within the housing. A channel for transmitting light is mounted within the input device. A user touches the head of the input device to enable a PPG detection function. In this way, the PPG detection function of the wearable device can be implemented without significantly increasing the size of the wearable device, thereby achieving a miniaturized design of the device and improving the user experience overall.

[0006] In a first aspect, a wearable device is provided, which includes: a shell including a mounting hole; an input device including a rod and a head connected to each other, the rod being arranged on the shell through the mounting hole, the head being arranged at one end of the rod, and the head being located outside the mounting hole; a circuit board arranged in the shell; a processor and a PPG sensor, the processor and the PPG sensor being connected to the circuit board, the processor being arranged in the shell, and the PPG sensor being arranged in the rod or the head; a fifth channel being arranged in the input device and extending from the outer surface of the head to the PPG sensor, for transmitting a light signal reflected by a measured object to the PPG sensor, so that the processor obtains the physiological parameters of the measured object

[0007] The outer surface of the head includes an outer end surface of the head and a side surface of the head, wherein the outer end surface of the head is parallel or approximately parallel to the side surface of the shell, and the side surface of the head is a surface in the circumferential direction of the head.

[0008] The wearable device provided in an embodiment of the present application is provided with an input device, and the stem or head of the input device is provided with a PPG sensor. When a user touches the head of the input device, the light signal reflected by the user passes through a channel within the input device and reaches the PPG sensor. The processor obtains the light signal reflected by the measured object through the PPG sensor and processes the light signal to obtain the physiological parameters of the measured object, completing the PPG detection. In this way, the PPG detection function of the wearable device can be realized without significantly increasing the size of the wearable device, achieving a miniaturized design of the device and improving the user experience overall.

[0009] In some embodiments, the wearable device may be a watch, and the input device may be a crown of the watch.

[0010] Optionally, the wearable device further includes a connector, at least a portion of which is disposed within the rod portion, the connector being disposed between the circuit board and the PPG sensor, and both ends of the connector being connected to the circuit board and the PPG sensor, respectively.

[0011] In the embodiment of the present application, by providing a connector connecting the PPG sensor and the circuit board on the rod portion of the input device, the space of the rod portion is effectively utilized, the space occupied by the housing is reduced, and the electrical connection between the PPG sensor and the processor can be achieved. Especially for the structure in which the PPG sensor is provided on the head, it is more effective to provide a connector on the rod portion and it is easy to implement.

[0012] Optionally, the PPG sensor is fixedly connected to the rod or the head to drive the PPG sensor to rotate when the input device is rotated, wherein,

[0013] The connector includes a first connector and a second connector, the second connector and the first connector are rotatable relative to each other, the second connector is connected to the PPG sensor, and the first connector is connected to the circuit board, so that when the input device is rotated and the PPG sensor is rotated, the first connector does not rotate, but the second connector rotates.

[0014] Optionally, the PPG sensor is fixedly connected to the rod or the head to drive the PPG sensor to rotate when the input device is rotated, wherein the connector includes a first connecting member and a second connecting member, the second connecting member and the first connecting member are rotatable relative to each other, the first connecting member is connected to the PPG sensor, and the second connecting member is connected to the circuit board, so that when the input device is rotated and drives the PPG sensor to rotate, the second connecting member does not rotate, and the first connecting member rotates.

[0015] In the wearable device provided in the embodiment of the present application, the PPG sensor is fixed in the input device, and the first connector and the second connector of the connector are rotatably connected. One connector is connected to the circuit board, and the other connector is connected to the PPG sensor. This allows the PPG sensor to rotate when the input device is rotated, and allows the connector connected to the PPG sensor to rotate, while the other connector connected to the circuit board does not rotate. In a wearable device with this structure, the input device can be installed first and then the PPG sensor and the connector, or the PPG sensor and the connector can be installed first and then the input device. This makes the wearable device easy to install and has high design flexibility.

[0016] In some embodiments, the second connecting member is disposed in the rod portion and includes a plurality of second electrodes spaced apart along the axial direction of the rod portion, the second electrodes being connected to the PPG sensor.

[0017] The first connecting member is disposed in the housing and is located on a side of the rod away from the head, and includes a plurality of first electrodes. The first electrodes are connected to the circuit board. The first electrodes are in a ring structure. One of any two first electrodes surrounds the other first electrode. The plurality of first electrodes corresponds to the plurality of second electrodes in a one-to-one manner.

[0018] When the input device is rotated and drives the PPG sensor to rotate, the second electrode may rotate on the corresponding first electrode to contact the corresponding first electrode, so as to maintain the connection between the first connector and the second connector.

[0019] The wearable device provided in the embodiment of the present application has only the second connector of the connector provided on the rod portion of the input device. Therefore, the wearable device does not have excessive requirements on the radial size of the rod portion of the input device. That is, the radial size of the rod portion can be designed to be smaller, which reduces the size of the mounting hole to a certain extent and avoids the problem of poor structural strength caused by the larger size of the mounting hole.

[0020] In some other embodiments, the first connecting member is disposed within the rod portion with a gap therebetween, and includes a first body and at least one first metal member fixed to the first body, wherein the first body is a cylindrical structure, and the first metal member includes a first connecting segment and a first contact segment connected to each other, wherein one end of the first connecting segment is connected to the circuit board, and the first contact segment extends into the interior of the first body.

[0021] The second connecting member is sleeved in the first body and rotatably connected to the first connecting member, including a second body and at least one second metal member fixed to the second body, the second body is a cylindrical structure, the second metal member includes a second connecting segment and a second contact segment connected to each other, one end of the second connecting segment is connected to the PPG sensor, and the second contact segment is sleeved on the second body, wherein at least one first metal member corresponds to at least one second metal member in a one-to-one manner.

[0022] When the input device is rotated and drives the PPG sensor to rotate, the second connecting member rotates and the first connecting member does not rotate, and the second contact segment of the second metal member can contact the corresponding first contact segment of the first metal member to maintain the connection between the first connecting member and the second connecting member.

[0023] The wearable device provided in the embodiment of the present application does not occupy space in the housing and has better reliability because most of the two connecting parts of the connector are arranged on the rod portion.

[0024] In other embodiments, the wearable device further includes a sensor for detecting rotation or movement of the input device, wherein the sensor is connected to the circuit board and extends into the cavity of the second body.

[0025] The wearable device provided in the embodiment of the present application sets the sensor for detecting the rotation or movement of the input device in the cavity of the second body of the connector. Since the space of the connector is fully utilized, the space occupied by the sensor in the shell is reduced, which can reduce the volume of the wearable device to a certain extent and realize the miniaturized design of the wearable device.

[0026] Optionally, there is a gap between the PPG sensor and the input device, the connector is sleeved inside the rod and has a gap between the connector and the rod, and when the input device is rotated, the PPG sensor and the connector do not rotate.

[0027] In the wearable device provided in the embodiment of the present application, the PPG sensor and the input device have a gap and do not contact each other, and the connector sleeved inside the rod has a gap and does not contact each other, so that when the input device is rotated, neither the PPG sensor nor the connector rotates. Since the PPG sensor does not rotate, the fingerprint recognition function is easily and stably implemented. Moreover, since the connector does not rotate, the reliability of the connector can be ensured as much as possible.

[0028] In a second aspect, a wearable device is provided, which includes: a shell including a mounting hole; an input device including a connected rod and a head, the rod being arranged on the shell through the mounting hole, the head being arranged at one end of the rod, and the head being located outside the mounting hole; a circuit board being arranged in the shell; a processor and a PPG sensor, the processor and the PPG sensor being connected to the circuit board, the processor being arranged in the shell, and the PPG sensor being arranged in the shell and on a side close to the inner end face of the rod; a sixth channel being arranged in the input device and extending from the outer surface of the head to the inner end face of the rod, the sixth channel being used to transmit the light signal reflected by the object to be measured to the PPG sensor, so that the processor obtains the physiological parameters of the object to be measured.

[0029] The inner end surface of the rod portion is an end surface perpendicular to the axial direction of the rod portion and away from the head portion.

[0030] The wearable device provided in an embodiment of the present application is provided with an input device, and a PPG sensor is provided in the housing of the wearable device. When a user touches the head of the input device, the light signal reflected by the user passes through the channel in the input device to reach the PPG sensor. The processor obtains the light signal reflected by the object under test through the PPG sensor and processes the light signal to obtain the physiological parameters of the object under test, completing the PPG detection. In this way, not only can the PPG detection function of the wearable device be realized, but the volume of the wearable device will not be significantly increased, thereby realizing a miniaturized design of the device and improving the user experience overall. In some embodiments, the wearable device also includes an infrared light transmitting unit and an infrared light channel.

[0031] In one feasible manner, the infrared light sending unit is arranged in the rod or the head; the infrared light channel extends from the outer surface of the head to the infrared light sending unit, and is used to transmit the infrared light emitted by the infrared light sending unit to the object to be measured.

[0032] In another feasible embodiment, the infrared light sending unit is arranged in the shell and on one side close to the inner end surface of the rod; the infrared light channel is arranged in the input device and extends from the outer surface of the head to the inner end surface of the rod, for transmitting the infrared light emitted by the infrared light sending unit to the object to be measured.

[0033] The infrared light signal emitted by the infrared light sending unit set in the wearable device can be transmitted to the part to be detected through the infrared light channel, so that the part to be detected can absorb the energy radiated by the infrared light signal, improve the signal quality of the user's skin and blood vessels, and thus improve the quality of PPG detection of the wearable device.

[0034] In some embodiments, the wearable device further includes an ECG electrode, which is disposed on the outer end surface of the head or the side of the head, and the ECG electrode includes a raised portion and a flat portion, wherein the flat portion of the ECG electrode is disposed close to a side of the input device, and the raised portion is disposed away from a side of the input device, and the raised portion is used to increase the humidity of the ECG electrode.

[0035] The ECG electrode with the raised portion increases the contact area between the ECG electrode and the skin when the skin contacts the ECG electrode. Furthermore, the ECG electrode with the raised portion facilitates the condensation of water vapor in the environment. When moisture accumulates to a certain level, large water droplets can form. When the diameter of the large water droplets is larger than the maximum span of the raised portion, they will diffuse or dissipate through the hydrophobic surface of the gap, ensuring that water vapor condenses on the raised portion while preventing the water droplets from being too large. Furthermore, the surface of the ECG electrode can lock in moisture in the environment, thus keeping the surface of the ECG electrode moist, reducing the impedance between the ECG electrode and the skin, and making the polarized ECG electrode more stable. As a result, the wearable device can collect better quality electrical signals by setting up the ECG electrode with the raised portion, thereby improving the accuracy of ECG detection on the wearable device.

[0036] In some embodiments, the wearable device further includes: a temperature control device, which is disposed on a side of the ECG electrode close to the input device, and is used to change the temperature of the ECG electrode when the temperature control device is powered on.

[0037] The temperature of the ECG electrodes can be changed by the temperature control device, so that the quality of the electrical signals collected by the wearable device is better, thereby improving the accuracy of ECG detection of the wearable device.

[0038] In some embodiments, the temperature control device includes: a cooling plate and / or a heating plate, wherein the cooling plate is used to reduce the temperature of the ECG electrode, and the heating plate is used to increase the temperature of the ECG electrode.

[0039] The cooling element in the temperature control device can keep the ECG electrodes at a constant low temperature, making it easier for moisture in the environment to condense. The heating element in the temperature control device can heat the electrodes, reducing the impedance between the skin and the electrodes, so that the electrical signals collected by the wearable device are of better quality, thereby improving the accuracy of the wearable device's ECG detection.

[0040] In a third aspect, a wearable device is provided, which includes a processor, an input device and a locking mechanism, wherein the locking mechanism is connected to the processor and the input device, respectively. After detecting a second operation, the processor controls the locking mechanism to fix the input device so that the input device cannot be moved and / or rotated.

[0041] The locking mechanism can keep the input device stable, thereby improving the accuracy of ECG detection or PPG detection of the wearable device.

[0042] In a fourth aspect, a detection method is provided, which is applied to a wearable device, the wearable device including a housing, a first input device, and at least one PPG sensor, the housing including a mounting hole, the first input device including a connected rod and a head, the rod being mounted on the housing through the mounting hole, the head being mounted at one end of the rod and located outside the mounting hole, and a circuit board being mounted within the housing; a processor and a PPG sensor, both connected to the circuit board, the processor being mounted within the housing, the at least one PPG sensor being mounted within the rod, the head, or the housing and adjacent to a side of an inner end surface of the rod; a fifth channel being mounted within the input device and extending from an outer surface of the head to the PPG sensor, the method comprising: detecting a first operation, the first operation being an operation of starting physiological parameter measurement; in response to the first operation, the at least one PPG sensor acquiring, via the fifth channel, an optical signal reflected by a measured object; the processor receiving the optical signal sent by the at least one PPG sensor; and acquiring, based on the optical signal, a physiological parameter of the measured object.

[0043] When the user activates the physiological parameter measurement function, the light signal reflected by the user passes through the channel within the input device and reaches the PPG sensor. The processor then acquires the light signal reflected by the measured object through the PPG sensor and processes it to obtain the measured object's physiological parameters, completing the PPG measurement. This not only enables the PPG measurement function of the wearable device, but also does so without significantly increasing the size of the wearable device, achieving a miniaturized design and improving the overall user experience.

[0222] The wearable device provided in the embodiments of the present application is a portable device that can be integrated into a user's clothing or accessories, has computing capabilities, and can be connected to a mobile phone and various terminal devices. For example, the wearable device can be a watch, a smart wristband, a portable music player, a health monitoring device, a computing or gaming device, a smartphone, an accessory, etc. In some embodiments, the wearable device can be a watch worn around the user's wrist.

[0223] The wearable device provided in the embodiments of the present application is a device that includes input devices such as a crown, a switch, a button or a key, reuses the input devices already on the wearable device, and integrates fingerprint recognition, photography, PPG detection, gas detection, ambient light detection, body temperature detection, luminous lighting and other functions on the input device, which can greatly improve the user experience without significantly increasing the size of the device. In addition, in other embodiments, the rotation or movement of the input device can be identified through relevant designs. In addition, in some other embodiments, the extension or locking of the input device can be achieved through relevant designs.

[0224] Figure 1 1 is a schematic functional block diagram of a wearable device provided in some embodiments of the present application. For example, the wearable device 100 may be a smart watch or a smart bracelet. Figure 1 , exemplarily, the wearable device 100 may include a processor 110, an input device 120, a sensor module 130, a memory 160 and a power supply module 170. It is understood that, Figure 1 The components shown do not constitute a specific limitation on the wearable device 100. The wearable device 100 may also include more or fewer components than shown, or combine or split some components, or arrange the components differently.

[0225] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). The different processing units may be independent devices or integrated into one or more processors. The controller may be the nerve center and command center of the wearable device 100. The controller may generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution. In other embodiments, the processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that have just been used or are recycled by the processor 110. If the processor 110 needs to use the instruction or data again, it can be directly called from the memory, avoiding repeated access, reducing the waiting time of the processor 110, and thus improving the efficiency of the wearable device 100.

[0226] The input device 120 is used to provide user input and can be a mechanical device. The user touches the input device 120, causing the input device 120 to rotate, translate or tilt to realize user input, so as to realize functions or operations such as starting the wearable device 100 (for example, turning on or off), determining or adjusting signals (for example, adjusting the volume), etc.

[0227] It is understood that user input in the embodiments of the present application can be operations such as rotation, translation, and tilting of the input device 120 by the user. Among them, the translation and tilting operations of the input device 120 by the user can be collectively referred to as movement operations of the input device 120 by the user. Therefore, user input in the embodiments of the present application can include rotation input and movement input. For example, the user can rotate the input device 120 by sliding or rolling the input device 120, and the user can move the input device 120 by pressing the input device 120.

[0228] It is understood that the input device 120 can be a single component or a combination of multiple components. In some embodiments, the input device 120 can include a button that can implement rotational input. For example, the button can also implement movement input such as tilting or translation. In an embodiment where the wearable device 100 is a smartwatch, the button can also be called a crown. In other embodiments, the input device 120 can include a key that can implement movement input such as tilting or pressing. For example, the key can be a power key or a volume key of the wearable device 100. In other embodiments, the input device 120 can include a button and a key.

[0229] It will also be appreciated that the wearable device 100 may include one or more input devices 120 .

[0230] In other embodiments, the input device 120 can implement multiple functions. For example, the input device 120 can implement fingerprint recognition, photoplethysmography (PPG) detection, photography, gas detection, ambient light detection, body temperature detection, and lighting, among other functions. The details are described in detail below. PPG can also be referred to as photoplethysmography, and the two descriptions are interchangeable.

[0231] The sensor module 130 may include one or more sensors, for example, a PPG sensor 130A, a pressure sensor 130B, a fingerprint sensor 130C, a capacitive sensor 130D, an acceleration sensor 130E, an ambient light sensor 130F, a proximity light sensor 130G, a touch sensor 130H, etc. It should be understood that Figure 1 These are just a few examples of sensors. In actual applications, the wearable device 100 may also include more or fewer sensors, or use other sensors with the same or similar functions to replace the above-mentioned sensors, etc., and the embodiments of the present application are not limited thereto.

[0232] In some embodiments, the sensor module 130 can detect user input from the input device 120 and respond to the user input to implement functions or operations such as starting, determining, and adjusting signals.

[0233] The PPG sensor 130A can be used to detect heart rate, that is, the number of heartbeats per unit time. In some embodiments, the PPG sensor 130A may include a light transmitting unit and a light receiving unit. The light transmitting unit can irradiate a light beam into the human body (such as a blood vessel), and the light beam is reflected / refracted in the human body, and the reflected / refracted light is received by the light receiving unit to obtain a light signal. Since the transmittance of the blood changes during the fluctuation process, the transmitted / refracted light changes, and the light signal detected by the PPG sensor 130A also changes. The PPG sensor 130A can convert the light signal into an electrical signal and determine the heart rate corresponding to the electrical signal. In an embodiment of the present application, the PPG sensor 130A can be set in the input device 120 or in the housing 180, and the PPG detection function can be achieved through the light signal detected by the PPG sensor 130A.

[0234] The pressure sensor 130B can be used to detect the pressure value between the human body and the wearable device 100. The pressure sensor 130B is used to sense the pressure signal and can convert the pressure signal into an electrical signal. There are many types of pressure sensors 130B, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc., which are not limited in the embodiment of the present application. In the embodiment of the present application, multiple pressure sensors 130B can be provided on the input device 120, and the rotation of the input device 120 can be identified by the signal difference between adjacent pressure sensors 130B among the multiple pressure sensors 130B.

[0235] Fingerprint sensor 130C is used to collect fingerprints. The wearable device 100 can use the collected fingerprint characteristics to achieve fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc. There are many types of fingerprint sensors 130C. For example, fingerprint sensor 130C may include optical fingerprint sensors, semiconductor fingerprint sensors, and ultrasonic sensors. Among them, semiconductor fingerprint sensors may include capacitive sensors, thermal sensors, pressure sensors, etc. In the embodiment of the present application, fingerprint sensor 130C can be set in the input device 120 or in the housing 180, and the fingerprint recognition function can be realized by light reflected by the input device 120.

[0236] The capacitance sensor 130D can be used to detect the capacitance between two electrodes to achieve specific functions.

[0237] In some embodiments, the capacitance sensor 130D can be used to detect the capacitance between the human body and the wearable device 100. The capacitance can reflect whether the contact between the human body and the wearable device is good, and can be applied to electrocardiography (ECG) detection, in which the human body can be used as an electrode. When the capacitance sensor 130D is set on the electrode on the wearable device, the capacitance sensor 130D can detect the capacitance between the human body and the electrode. When the capacitance detected by the capacitance sensor 105D is too large or too small, it means that the contact between the human body and the electrode is poor; when the capacitance detected by the capacitance sensor 130D is moderate, it means that the contact between the human body and the electrode is good. Since whether the contact between the human body and the electrode is good will affect the electrode detection electrical signal, and thus affect the generation of ECG, the wearable device 100 can refer to the capacitance detected by the capacitance sensor 130D when generating ECG.

[0238] In other embodiments, the capacitance sensor 130D may generate a change in capacitance between the capacitance sensor 130D and a metal electrode disposed in the input device 120 , and recognize the rotation or movement of the input device 120 through the change in capacitance.

[0239] Accelerometer 130E can be used to detect the magnitude of acceleration of wearable device 100 in various directions (generally three axes). Wearable device 100 is a wearable device. When a user wears wearable device 100, wearable device 100 moves under the influence of the user. Therefore, the magnitude of acceleration in various directions detected by accelerometer 130E can reflect the body's motion state.

[0240] The ambient light sensor 130F is used to sense ambient light parameters. For example, the ambient light parameters may include the ambient light intensity or the coefficient of ultraviolet rays in the ambient light.

The wearable device 100 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the wearable device 100. When insufficient reflected light is detected, the wearable device 100 can determine that there is no object near the wearable device 100. The wearable device 100 can use the proximity light sensor 130G to detect that the user is holding the wearable device 100 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor 130G can also be used in leather case mode and pocket mode to automatically unlock or lock the screen.

[0242] Touch sensor 130H can be disposed on a display screen. The touch sensor 130H and the display screen form a touch screen, also known as a "touch screen." Touch sensor 130H is configured to detect touch operations applied to or near the touch sensor 130H. Touch sensor 130H can transmit the detected touch operations to a processor to determine the type of touch event. Visual output related to the touch operations can be provided via the display screen. In other embodiments, touch sensor 130H can also be disposed on the surface of the display screen, at a different location from the display screen.

In some embodiments, the wearable device 100 may be a smart watch or a smart bracelet. Figure 2The wearable device 100 includes a main body 101 and two wristbands 102 ( Figure 2 The wristband 102 is shown in the figure). The wristband 102 can be fixedly connected or movably connected to the main body 101. The wristband 102 can be wrapped around the wrist, arm, leg or other parts of the body to fix the wearable device 100 to the user. The main body 101 may include a shell 180 and a cover 114. The shell 180 surrounds the cover 114. For example, the shell 180 includes a groove set at the top, and the cover 114 is accommodated in the groove. The edge of the cover 114 is adjacent to and fixed on the groove of the shell 180, forming a surface of the main body 101. The structure formed by the shell 180 and the cover 114 has an accommodating space inside, which can accommodate Figure 1 The combination of one or more components shown and not shown can realize various functions of the wearable device 100. The main body 101 also includes an input device 120. The receiving space within the structure formed by the cover 114 and the housing 180 can accommodate a portion of the input device 120, and the exposed portion of the input device 120 is convenient for the user to access.

[0261] The cover 114 serves as a surface of the main body 101 and can serve as a protective plate for the main body 101 to prevent the components housed in the housing 180 from being exposed and damaged. For example, the cover 114 can be transparent. For example, the cover 114 can include crystal, such as sapphire crystal, or can be formed of glass, plastic, or other materials.

[0262] In some embodiments, the cover 114 may be a display screen 140, through which a user may interact with the wearable device 100. For example, the display screen 140 may receive user input and, in response to the user input, make corresponding outputs. For example, a user may touch or press a graphic location on the display screen 140 to select (or otherwise) open or edit the graphic.

[0263] The input device 120 is attached to the outside of the housing 180 and extends to the inside of the housing 180. In some embodiments, the input device includes a head 121 and a stem 122 connected to each other. The stem 122 extends into the housing 180, and the head 121 is exposed outside the housing 180. It can serve as the part that contacts the user to allow the user to contact the input device and receive user input by rotating, tilting or translating the head 121. When the user operates the head 121, the stem 122 can move with the head 121. It can be understood that the head 121 can be of any shape. For example, the head 121 can be cylindrical. It can be understood that the rotatable input device 120 can be called a button. In an embodiment where the wearable device 100 is a watch, the rotatable input device 120 can be the crown of the watch. The input device 120 can be called a crown.

[0264] In an embodiment of the present application, in order to further improve the practicality of the wearable device 100, the input device 120 may also have one or more functions, so that the input device 120 with the above functions may have different specific structures in different embodiments, which is described in detail below.

[0265] The housing 180 can be made of a variety of materials, including but not limited to plastic, metal, and alloys. The housing 180 is provided with a mounting hole that mates with the input device 120 and accommodates the rod 122 of the input device 120. For example, a mounting hole extending into the interior of the housing 180 is provided on a side surface 180-A of the housing 180. Typically, the shape and size of the mounting hole mate with the rod 122. In other words, the shape and size of the mounting hole can be designed based on the rod 122.

[0266] It should be understood that the input device 120 is not limited to Figure 2 In the structure shown, any mechanical component that can receive user input can be used as the input device 120 in the embodiment of the present application.

[0267] In some embodiments, reference Figure 3 The input device 120 of the wearable device 100 can be a button 1201. The button 1201 can be used as an example of the input device 120. The button 1201 can be installed on the side 180-A of the shell 180. In an embodiment where the wearable device 100 is a watch, the button 1201 can be called a crown.

[0268] In other embodiments, continue to refer to Figure 3 The input device 120 of the wearable device 100 can be a button 1202. The button 1202 can be another example of the input device 120. The button 1202 can allow the user to press the button so that the button 1202 moves horizontally or tilted to achieve the user's mobile input.

[0269] In one example, the button 1202 may be mounted on the side 180 -A of the housing 180 , with a portion of the button 1202 exposed and another portion extending from the side of the housing 180 toward the interior of the housing 180 (not shown in the figure).

[0270] In another example, the key 1202 may also be provided on the head 121 of the button 1201, so as to realize both rotation input and movement input.

[0271] In another example, the button 1202 may also be provided on the top surface of the main body 101 on which the display screen 140 is installed.

[0272] In other embodiments, continue to refer to Figure 3The input device 120 may include a button 1201 and a key 1202. In one example, the button 1201 and the key 1202 may be disposed on the same surface of the housing 180, for example, on the same side of the housing 180. In another example, the button 1201 and the key 1202 may be disposed on different surfaces of the housing 180. This embodiment of the present application does not impose any limitation. It should be understood that the input device 120 may include one or more keys 1202, as well as one or more buttons 1201.

[0273] As previously mentioned, the purpose of the embodiments of the present application is to utilize the input device 120 to integrate functions such as fingerprint recognition, photography, PPG detection, gas detection, ambient light detection, body temperature detection, and luminous lighting on the wearable device 100, so as to improve the user experience without significantly increasing the size of the wearable device 100. In addition, the rotation or movement of the input device can be detected by designing a feature area on the input device 120 or the housing 180, and the retraction or locking of the input device can also be achieved through related designs.

[0274] The following describes in detail the structure for implementing the above functions in conjunction with the accompanying drawings.

[0275] The following, combined Figures 4 to 45 , describes the wearable device that realizes the fingerprint recognition function in the embodiment of the present application.

[0276] In this embodiment, the input device 120 can be designed with components related to fingerprint recognition installed in it. When a user touches the input device 120, they can achieve fingerprint recognition by rotating, pressing, moving, and / or tilting the input device 120. The fingerprint sensor 130C is the core component for fingerprint recognition and can identify the fingerprint based on the collected fingerprint information to determine the user's identity. The fingerprint sensor 130C can be various types of sensors. For example, the fingerprint sensor 130C can be an optical fingerprint sensor, a capacitive fingerprint sensor, or an ultrasonic fingerprint sensor.

[0277] In the embodiments of the present application, the fingerprint sensor 130C can be located in two locations within the wearable device 100. In some embodiments, the fingerprint sensor 130C can be located within the input device 120. In other embodiments, the fingerprint sensor 130C can also be located within the housing 180 of the wearable device 100. The following describes in detail the structural design for implementing fingerprint recognition in each of the above embodiments.

[0278] In an embodiment where the fingerprint sensor 130C is provided on the input device 120 , the fingerprint sensor 130C may be provided on the head portion 121 or the rod portion 122 of the input device 120 . When a finger contacts the head portion 121 , the fingerprint sensor 130C may obtain fingerprint information based on a signal from the head portion 121 to perform fingerprint recognition.

[0279] In some embodiments, the fingerprint sensor 130C may perform fingerprint recognition based on the collected fingerprint information. In other embodiments, the fingerprint sensor may send the collected fingerprint information to the processor 110 for fingerprint recognition to be performed by the processor 110.

[0280] In some embodiments, the fingerprint sensor 130C may remain stationary regardless of whether the input device 120 is rotated. In other embodiments, the fingerprint sensor 130C may rotate as the input device 120 rotates.

[0281] Figure 4 and Figure 5 1 is a schematic cross-sectional view of a partial area of ​​the wearable device 100 according to an embodiment of the present application. Figure 4 and Figure 5 Taking the fingerprint sensor 130C disposed on the head portion 121 of the input device 120 as an example, the structure of the wearable device having the fingerprint sensor 130C disposed on the head portion 121 is described using different types of fingerprint sensors 130C. It should be understood that the structure of the fingerprint sensor 130C disposed on the rod portion 122 is similar to that of the fingerprint sensor 130C disposed on the rod portion 122, and will not be further described.

[0282] In some embodiments, fingerprint sensor 130C is an optical fingerprint sensor. Figure 4 The structure shown can be applied to the scenario where the fingerprint sensor 130C is an optical fingerprint sensor.

[0283] refer to Figure 4The main body 101 of the wearable device 100 includes a housing 180, a cover 114, an input device 120, and a fingerprint sensor 130C. The cover 114 is connected to the top of the housing 180 to form the surface of the main body 101. In some embodiments, the cover 114 can be a display screen 140. A mounting hole 181 is provided on the housing 180. The input device 120 includes a head 121 and a rod 122. The rod 122 is installed in the mounting hole 181 to be mounted on the housing through the mounting hole 181. The head 121 extends outward from the housing 180 and accommodates a fingerprint sensor 130C. The fingerprint sensor 130C can be electrically connected to the first circuit board 111 located inside the housing 180 through a connector to send the fingerprint information detected by the fingerprint sensor 130C to the processor 110 installed on the first circuit board, and the fingerprint recognition is performed by the processor 110. The head 121 of the input device 120 is further provided with a channel for transmitting optical signals, which extends from the outer surface of the head 121 to the fingerprint sensor 130C, that is, one end of the channel is located on the outer surface of the head 121, and the other end is connected to the fingerprint sensor 130C so that the optical signal can be transmitted through the channel. For example, the channel can be a transparent area of ​​the head, which is made of a transparent material, such as Figure 4 As shown, the channel can be formed by a transparent cover 1211. For example, the head 121 can be made of a transparent material, and the area between the surface of the head 121 and the fingerprint sensor 130C can form a channel, which is not limited in this embodiment of the present application.

[0284] The outer surface of the head 121 includes an outer end surface 121-A and a side surface 121-B connected to each other. The outer end surface 121-A of the head 121 is approximately parallel to the side surface 180-A of the housing 180. The side surface 121-B of the head 121 is a circumferential surface of the head 121. In some embodiments, the channel extends from the outer end surface 121-A of the head 121 to the fingerprint sensor (e.g., Figure 4 cover 1211 shown); in other embodiments, the channel extends from the side 121-B of the head 121 to the fingerprint sensor.

[0285] In an embodiment where fingerprint sensor 130C is an optical fingerprint sensor, the optical fingerprint sensor includes a light receiving unit. Light emitted from the light emitting unit within housing 180 can pass through the channel of head 121 to reach a finger pressed against the outer surface of head 121. Light reflected from the finger passes through the channel and is projected onto the optical fingerprint sensor. The optical fingerprint sensor generates fingerprint information based on the projected light for fingerprint recognition. In other embodiments, the light emitting unit can be integrated into the optical fingerprint sensor, that is, the optical fingerprint sensor can include both the light emitting unit and the light receiving unit.

[0286] In other embodiments, the fingerprint sensor 130C may also be a capacitive fingerprint sensor. Figure 5 The structure shown can be applied to the scene where the fingerprint sensor is a capacitive sensor. Figure 4 In comparison, Figure 5 In the illustrated structure, the head portion 121 of the input device 120 does not need to be provided with a channel. A capacitive sensor utilizes the electric field formed by the capacitive sensor and the conductive subcutaneous electrolyte. The fluctuations of the fingerprint cause the pressure difference between the two to vary, thereby achieving accurate fingerprint measurement. When a finger presses the surface of the capacitive sensor, the capacitive sensor generates a charge difference based on the peaks and troughs of the fingerprint, thereby forming fingerprint information for fingerprint recognition.

[0287] In other embodiments, the fingerprint sensor 130C may also be an ultrasonic sensor. Figure 5 The illustrated structure can also be applied to scenarios where the fingerprint sensor is an ultrasonic sensor. Ultrasonic sensors utilize the energy reflected by ultrasound waves from the finger surface. The reflectivity of ultrasonic energy varies between the valleys and ridges of a fingerprint. The reflected ultrasound waves are converted into electrical signals of varying intensities, ultimately forming a fingerprint image that alternates between light and dark, enabling accurate fingerprint measurement. When a finger presses against the surface of the ultrasonic sensor, the sensor generates fingerprint information based on the difference in reflected signals between the peaks and valleys of the fingerprint wave, enabling fingerprint recognition.

[0288] In the above Figure 4 or Figure 5 In the embodiment shown, the fingerprint sensor 130C can send fingerprint information to the processor 110 so that the processor 110 can perform fingerprint recognition based on the fingerprint information, or the fingerprint sensor 130C can complete fingerprint recognition based on the fingerprint information and transmit the fingerprint recognition result to the processor 110 so that the processor 110 can provide information to the user through an output device such as the display screen 140 of the wearable device 100 based on the result. It can be understood that in this embodiment, the data is transmitted between the fingerprint sensor 130C and the processor 110, and further reference is made to Figure 4 or Figure 5 The wearable device 100 also includes a connector 200 provided on the input device 120. The connector 200 can be used to realize an electrical connection between the fingerprint sensor 130C and the processor 110. Exemplarily, at least a portion of the connector 200 can be provided in the input device 120. For example, at least a portion of the connector 200 can be provided in the rod portion 122 of the input device 120. Here, at least a portion of the connector 200 represents part or all of the connector 200.

[0289] The processor 110 is mounted on a first circuit board 111 (also referred to as a mainboard) within the main body. The first circuit board 111 and the fingerprint sensor 130C are electrically connected via a connector 200. This electrically connects the processor 110 to the fingerprint sensor 130C. It should be understood that the processor 110 can be mounted directly on the first circuit board 111 or via another circuit board, without limitation.

[0290] The input device 120 can be rotated about the axial direction (e.g., the x-direction) of the shaft 122. Since the fingerprint sensor 130C is disposed within the input device 120, the fingerprint sensor 130C can rotate along with the rotation of the input device 120. Alternatively, the input device 120 can rotate while the fingerprint sensor 130C does not rotate, or neither the input device 120 nor the fingerprint sensor 130C can rotate. The following describes the connector 200 used to connect the fingerprint sensor 130C and the processor 110, and the relationship between the connector 200 and related components, using two embodiments in which the fingerprint sensor 130C rotates and one in which it does not rotate as examples.

[0291] In some embodiments, the fingerprint sensor 130C can rotate as the input device 120 rotates. The connector 200 may include a first connector and a second connector that are rotatably connected, wherein one connector is connected to the fingerprint sensor 130C, and the other connector is connected to the first circuit board 111 (or the processor 110). When the input device 120 is rotated, the fingerprint sensor 130C and the connector connected to the fingerprint sensor 130C can be driven to rotate, while the connector connected to the first circuit board 111 does not rotate. The rotational connection between the first connector and the second connector can realize an electrical connection between the first connector and the second connector, so as to realize an electrical connection between the fingerprint sensor 130C and the processor 110 set on the first circuit board.

[0292] The wearable device 100 of this structure can install the input device 120 first and then install the fingerprint sensor 130C and the connector 200, or can install the fingerprint sensor 130C and the connector 200 first and then install the input device 120, making the wearable device 100 easy to install and having high design flexibility.

[0293] Figure 6 It is a schematic structural diagram of the connector 200 provided in an embodiment of the present application.

[0294] refer to Figure 6The connector 200 includes a first connecting member 210 and a second connecting member 220 that are rotatably connected. The first connecting member 210 is electrically connected to the first circuit board in the main body 101, and the second connecting member 220 is electrically connected to the fingerprint sensor 130C. When the input device 120 is rotated and drives the fingerprint sensor 130C to rotate, the second connecting member 220 can rotate and the first connecting member 220 does not rotate.

[0295] Exemplarily, the first connecting member 210 is distributed in concentric circles and includes a plurality of annular electrodes 211, and one electrode 211 of any two electrodes 211 encloses the other electrode 211; the second connecting member 220 includes a plurality of electrodes 221 distributed in parallel along the axial direction (for example, the x direction) of the rod portion of the input device, and the plurality of electrodes 221 of the second connecting member 220 correspond one-to-one to the plurality of electrodes 211 of the first connecting member 210, and the electrodes 221 of the second connecting member 220 contact the corresponding electrodes 211 of the first connecting member 210 to realize the connection between the first connecting member 210 and the second connecting member. The electrical connection of the connector 220 can drive the fingerprint sensor 130C and the second connector 220 of the connector 200 to rotate when the input device 120 is rotated. The electrode 221 of the second connector 220 rotates on the corresponding electrode 211 of the first connector 210, so that the electrode 221 of the second connector 220 and the electrode 211 of the first connector 210 can always maintain good contact, so as to achieve a better electrical connection between the first connector and the second connector, thereby achieving an electrical connection between the fingerprint sensor 130C and the first circuit board through the connector 200. Figure 6 The figure shows four electrodes 211 of the first connecting member 210 and four electrodes 221 of the second connecting member 220, with one electrode 211 corresponding to one electrode 221. It can be seen that when the electrode 221 rotates, the movement trajectory of the electrode 221 is similar to the shape of the electrode 211, and the electrode 221 can always maintain contact with the electrode 211, thereby realizing the electrical connection between the fingerprint sensor 130C and the processor 110 on the first circuit board.

[0296] The following, combined Figures 7 to 11 The connector 200 and the relationship between the connector 200 and related components are described.

[0297] Figure 7 is a schematic exploded view of the connector 200 provided in an embodiment of the present application, Figure 8 It is a schematic assembly diagram of the connector 200 provided in an embodiment of the present application.

[0298] refer to Figure 7 and Figure 8The connector 200 includes a first connector 210 and a second connector 220. The first connector 210 includes a third body 212 and an annular electrode 211 fixedly connected to the third body 212. The first connector 210 can be electrically connected to the first circuit board 111 in the housing 180 and fixedly connected to the housing. Exemplarily, the first connector 210 is fixed to the housing by fixing the third body 212 to the housing. For example, a fastening hole 2121 is provided on the third body 212, and the third body 212 can be fixed to the housing by a fastener installed in the fastening hole 2121. The second connecting member 220 can be electrically connected to the fingerprint sensor 130C and is arranged in the rod portion 122 of the input device 120. It includes a fourth body 222 and an electrode 221 fixedly connected to the fourth body 222. The fourth body 222 is provided with a mounting hole 2221 for mounting the electrode 221. The electrode 221 can include a metal strip 2211. The two ends of the metal strip 2211 are respectively connected to the electrode 211 and the fingerprint sensor 130C.

[0299] In some embodiments, to ensure more stable contact between the electrode 221 and the electrode 211, the electrode 221 may further include an elastic member 2212. For example, the elastic member 2212 may be a spring, with its ends connected to the metal strip 2211 and the fingerprint sensor 130C, respectively. That is, the electrode 221 includes a fixedly connected metal strip 2211 and the elastic member 2212, with the end of the metal strip 2211 away from the elastic member 2212 connected to the electrode 211, and the end of the elastic member 2212 away from the metal strip 2211 electrically connected to the fingerprint sensor 130C. In embodiments where the electrode 221 of the second connector 220 includes the metal strip 2211 and the elastic member 2212, the electrode 221 may be referred to as a spring.

[0300] Figure 9 The embodiment of the present application provides an installation having Figures 6 to 8 A schematic exploded view of the wearable device 100 showing the connector 200 is shown. Figure 10 The embodiment of the present application provides an installation having Figures 6 to 8 A schematic assembly diagram of the wearable device 100 with the connector 200 is shown, Figure 11 The embodiment of the present application provides an installation having Figures 6 to 8 The schematic assembly diagram of the local area of ​​the wearable device 100 of the connector 200 is shown. It should be understood that Figures 9 to 11 The structure shown is merely for illustrative purposes; the wearable device 100 may include more or fewer components, and the positions and connection relationships between the components in the wearable device 100 are not limited to the structure shown in the figure.

[0301] refer to Figures 9 to 11The main body 101 of the wearable device 100 includes a housing 180 , a first circuit board 111 , a connector 200 , a fingerprint sensor 130C, and an input device 120 . Exemplarily, the fingerprint sensor 130C is fixed to the head 121 of the input device 120 .

[0302] In some embodiments, the main body 101 further includes a cover plate 1211 fixed to an end of the head portion 121, which is configured to contact a finger to protect components disposed within the head portion 121 (e.g., the fingerprint sensor 130C). For example, in an embodiment where the fingerprint sensor 130C is an optical fingerprint sensor, the cover plate 1211 can be understood as a channel disposed in the head portion 121 and made of a transparent material. For example, the cover plate 1211 can be a transparent glass cover plate.

[0303] In other embodiments, the main body 101 further includes a second circuit board 112 (which may be referred to as a small board) electrically connected to the fingerprint sensor 130C, and one end of the connector 200 may be electrically connected to the fingerprint sensor 130C through the second circuit board 112 .

[0304] Continue to refer Figures 9 to 11 The first connector 210 of the connector 200 is disposed inside the housing 180 and fixed to the housing 180. An end of the first connector 210 away from the second connector 220 is electrically connected to the first circuit board 111. The second connector 220 of the connector 200 is sleeved inside and fixedly connected to the rod 122 of the input device 120. An end of the second connector 220 away from the first connector 210 is electrically connected to the fingerprint sensor 130C. For example, an end of the electrode 221 of the second connector 220 away from the first connector 210 is electrically connected to the fingerprint sensor 130C. For example, an end of the elastic member 2212 of the electrode 221 of the second connector 220 is electrically connected to the fingerprint sensor 130C. One end of the second connector 220 close to the first connector 210 is electrically connected to the first connector 210. Specifically, the annular electrode of the first connector 210 corresponds one-to-one to the electrode 221 of the second connector 220. An annular electrode of the first connector 210 contacts the corresponding electrode 221 of the second connector 220. Exemplarily, an annular electrode of the first connector 210 contacts one end of the metal strip 2221 of the corresponding electrode 221 of the second connector 220.

[0305] When the input device 120 is rotated along the axial direction of the rod 112, the input device 120 drives the fingerprint sensor 130C and the second connecting member 220 to rotate, so that the electrode 221 of the second connecting member 220 is always in contact with the electrode of the first connecting member 210 to maintain the electrical connection between the fingerprint sensor 130C and the first circuit board 111.

[0306] In this embodiment, the connector 200 includes a second connector 220 and a first connector 210 that are rotatably connected. The second connector 220 is connected to the fingerprint sensor 130C, and the first connector 210 is connected to the first circuit board 111. The second connector 220 is disposed on the rod 122, and the first connector 210 is disposed within the housing 180. During the rotation of the fingerprint sensor 130C, an electrical connection between the fingerprint sensor 130C and the first circuit board 110 can be achieved. Since the rod 122 can only be provided with the second connector 220, the wearable device 100 of this structure does not have too many restrictions on the radial size of the rod 122. However, the first connector 210 disposed within the housing 180 will occupy part of the space of the housing 180, and since the second connector 220 and the first connector 210 need to be aligned, certain requirements are placed on the installation accuracy of the connector 200.

[0307] In embodiments where the fingerprint sensor 130 rotates, another embodiment of the present application provides a connector. This connector 200 includes two coaxially arranged sleeves that are rotatably connected along a circumferential direction to maintain electrical connection. These sleeves are referred to as a first connector (or outer sleeve) and a second connector (or inner sleeve). The second connector is inserted within the first connector, and the second and first connectors maintain contact with each other to achieve electrical connection. The rotatable connection between the second and first connectors indicates that one of the second and first connectors is fixedly connected to the fingerprint sensor 130C and rotatable, while the other sleeve is fixedly connected to the first circuit board 111 (or mainboard) within the housing and cannot rotate. When the input device 120 is rotated, the fingerprint sensor 130C and the sleeve electrically connected to the fingerprint sensor rotate. Furthermore, due to the rotatable connection between the two sleeves, one sleeve maintains contact with the other sleeve during rotation, maintaining electrical connection between the fingerprint sensor 130C and the first circuit board 111.

[0308] The following, combined Figures 12 to 19 , explain the connector and the relationship between the connector and related components.

[0309] Figure 12 is a schematic exploded view of a connector 200 provided in another embodiment of the present application. Figure 13 is a schematic structural diagram of a first body provided in another embodiment of the present application, Figure 14 is a schematic structural diagram of a first connecting member provided in another embodiment of the present application, Figure 15 is a schematic structural diagram of a second body provided in another embodiment of the present application, Figure 16 is a schematic structural diagram of a second connecting member provided in another embodiment of the present application, Figure 17 This is a schematic assembly diagram of a connector provided in another embodiment of the present application.

[0310] refer to Figures 12 to 14 The first connector 210 includes a first body 241 and at least one first metal member 242 fixedly connected to the first body 241. A portion of the first metal member 242 is exposed inside the first body 241 and can contact the metal member on the second connector 220 to achieve electrical connection between the first connector 210 and the second connector 220. One end of the first metal member 242 extending from the first body 241 can be electrically connected to related components. For example, one end of the first metal member 242 can be electrically connected to the first circuit board 111 (or main board) in the housing 180, and can also be electrically connected to the fingerprint sensor 130C. When one end of the first metal member 242 is electrically connected to the first circuit board 111, the first connector 210 does not rotate. When one end of the first metal member 242 is electrically connected to the fingerprint sensor 130C, the first connector 210 can rotate.

[0311] It should be understood that when the first connector 210 includes multiple first metal members 242, any two first metal members 242 may or may not be in contact with each other, and this embodiment of the application does not impose any limitation. For example, the number of first metal members 242 can be four.

[0312] In some embodiments, reference Figure 12 and Figure 13 As shown, the outer wall 2411 of the first body 241 is provided with a first groove 2412 corresponding to the first metal member 242, and the first groove 2412 extends from the outer wall 2411 of the first body 241 to the end of the first body 241, and the first groove 2412 is provided with an opening 2412-1. Figure 12 and Figure 14 The first metal part 242 is inserted into the first groove 2412 to be clamped on the first body 241. The part of the first metal part 242 located at the position of the opening 2412-1 (referred to as the first contact section 2421) is exposed inside the first body 241 and can contact the annular metal part of the second connecting member 220. The remaining part of the first metal part 242 (referred to as the first connecting section 2422) extends toward the outside of the first body 241. The end of the first metal part 242 extending out of the first body 241 can be electrically connected to the first circuit board 111 or the fingerprint sensor 130C.

[0313] For example, refer to Figure 13 The first groove 2412 includes a first groove segment 2412-A arranged along the circumferential direction of the first body 241 and a second groove segment 2412-B arranged along the axial direction of the first body 241. The first groove segment 2412-A and the second groove segment 2412-B are connected. Correspondingly, referring to Figure 12 and Figure 14The first connecting section 2422 of the first metal part 242 includes a connected ring section 2422-A and an extension section 2422-B, the ring section 2422-A is inserted into the first groove section 2412-A, and the extension section 2422-B is inserted into the second groove section 2412-B, and the extension section 2422-B extends out of one end of the first body 241 and is connected to the first circuit board 111 or the fingerprint sensor 130C.

[0314] For example, the first metal member 242 is an elastic metal member. When the first metal member 242 contacts the annular metal member of the second connector 220, it can elastically press against the annular metal member. Thus, during relative rotation between the first connector 210 and the second connector 220 about the axial direction, the elastic first metal member 242, with its good deformability, can effectively contact the metal member on the second connector 220, thereby ensuring electrical connection between the first connector 210 and the second connector 220.

[0315] Exemplarily, the first metal member 242 may be linear, for example, the first metal member 242 may be an elastic metal wire.

[0316] refer to Figure 12 、 Figures 15 to 17 The second connector 220 includes a second body 251 and at least one second metal member 252 fixedly connected to the second body 251. The at least one second metal member 252 corresponds one-to-one with the at least one first metal member 242 of the first connector 210. Specifically, the number of second metal members 252 is the same as the number of first metal members 242 of the first connector 210. In addition, the portion of the second metal member 252 that is mounted on the second body 251 can always be in contact with the first metal member 242 to achieve electrical connection between the first connector 210 and the second connector 220. The end of the second metal member 252 that extends out of the second body 251 can be electrically connected to related components. For example, one end of the second metal member 252 can be electrically connected to the first circuit board 111 (or mainboard) in the housing 180, and can also be electrically connected to the fingerprint sensor 130C. When one end of the second metal member 252 is electrically connected to the first circuit board 111 , the second connector 220 does not rotate. When one end of the second metal member 252 is electrically connected to the fingerprint sensor 130C, the second connector 220 can rotate.

[0317] It should be understood that when the second connector 220 includes multiple second metal members 252, any two second metal members 252 may or may not be in contact with each other, and this embodiment of the application does not impose any limitation. For example, the number of second metal members 252 can be four.

[0318] It should also be understood that the second connector 220 and the first connector 210 are electrically connected to different components. In some embodiments, the second connector 220 is electrically connected to the fingerprint sensor 130C, and the first connector 210 is electrically connected to the first circuit board 111. The first circuit board 111 is fixed to the housing 180 of the wearable device 100. In this way, the first connector 210 can be fixed to the housing via the first circuit board 111. When the input device 120 is rotated, the fingerprint sensor 130C and the second connector 220 can rotate, while the first connector 210 does not rotate. In other embodiments, the second connector 220 is electrically connected to the first circuit board 111, and the first connector 210 is electrically connected to the fingerprint sensor 130C. When the input device 120 is rotated, the fingerprint sensor 130C and the first connector 210 can rotate, while the second connector 220 does not rotate. For example, in this embodiment, the first connector 210 can also be fixed to the rod 122 to better secure the first connector 210.

[0319] In some embodiments, reference Figure 12 The second metal member 252 includes a second contact segment 2521 and a second connecting segment 2522. Figure 15 The second body 251 is provided with a through hole 2511 corresponding to the second metal member 252, referring to Figure 16 The second contact segment 2521 is sleeved onto the outer wall of the second body 251. The second connecting segment 2522 extends through the through hole 2511 into the second body 251 and extends along the axial direction of the second body 251. The end of the second connecting segment 2522 extending from the second body 251 can be electrically connected to the first circuit board 111 or the fingerprint sensor 130C. It will be appreciated that in embodiments where the second connecting member 220 includes multiple second metal members 252, the second connecting segments 2522 of the second metal members 252 can be flipped inside the second body 251 and extended toward the outside of the inner body 251. This prevents interference between the individual second metal members 252, making it relatively easy to arrange the second connecting segments 2522, and resulting in a simple and easily implemented structure.

[0320] In other embodiments, the second body 251 may not need to be provided with a through hole 2511 corresponding to the second metal member 252. For example, the second contact section 2521 of the second metal member 252 is mounted on the outer wall of the second body 251, and the second connecting section 2522 is bent and extends toward the outside of the second body 251 on the outer wall of the second body 251 (not shown in the figure). The end extending out of the second body 251 can be electrically connected to the first circuit board 111 or the fingerprint sensor 130C. However, the design of this structure is relatively complex.

[0321] refer to Figure 17The second metal part 252 of the second connecting member 220 corresponds to the first metal part 252 of the first connecting member 210. When one of the second connecting member 220 and the first connecting member 210 rotates and the other does not rotate, the first contact segment 2421 of the first metal member 242 and the second contact segment 2521 of the second metal member 252 can always be in contact to achieve electrical connection between the second connecting member 220 and the first connecting member 210.

[0322] For the convenience of description, the second connecting member 220 is fixedly connected to the fingerprint sensor 130C and the first connecting member 210 is fixedly connected to the first circuit board 111 as an example. Figure 18 and 19 , explain the relationship between the connector and related components.

[0323] Figure 18 The embodiment of the present application provides an installation having Figures 12 to 17 A schematic exploded view of the wearable device 100 showing the connector 200 is shown. Figure 19 The embodiment of the present application provides an installation having Figures 12 to 17 The schematic assembly diagram of the local area of ​​the wearable device 100 of the connector 200 is shown. It should be understood that Figure 18 and Figure 19 The structure shown is merely for illustrative purposes; the wearable device 100 may include more or fewer components, and the positions and connection relationships between the components in the wearable device 100 are not limited to the structure shown in the figure.

[0324] refer to Figure 18 and Figure 19 The main body 101 of the wearable device 100 includes a housing 180 , a first circuit board 111 , a connector 200 , a fingerprint sensor 130C, and an input device 120 .

[0325] The fingerprint sensor 130C is fixed to the head 121 of the input device 120. In some embodiments, the main body 101 further includes a cover 1211 fixed to the end of the head 121, which is configured to contact a finger and protect the components disposed within the head 121 (e.g., the fingerprint sensor 130C). For example, in an embodiment where the fingerprint sensor 130C is an optical fingerprint sensor, the cover 1211 can be understood as a channel disposed in the head 121 and made of a transparent material. For example, the cover 1211 can be a transparent glass cover.

[0326] In other embodiments, the main body 101 further includes a second circuit board 112 (which may be referred to as a small board) electrically connected to the fingerprint sensor 130C, and one end of the connector 200 may be electrically connected to the fingerprint sensor 130C through the second circuit board 112 .

[0327] The connector 200 is internally mounted on the rod portion 122 of the input device 120. Specifically, the first connector 210 is internally mounted on the rod portion 122, with a gap between the first connector 210 and the rod portion 122 (not shown in the figure) so that the first connector 210 is not moved when the input device 120 is rotated. The second connector 220 is internally mounted on the first connector 210. The multiple first metal members 242 (e.g., four first metal members 242) of the first connector 210 correspond one-to-one with the multiple second metal members 252 (e.g., four second metal members 252) of the second connector 220. The first contact segment 2421 of the first metal member 242, located on the opening 2414-1 of the slot 2412 of the first body 241, contacts the second contact segment 2521 mounted on the second body 251, thereby achieving electrical connection between the second connector 220 and the first connector 210. One end of the first connecting section 2422 of the first connecting member 210, extending toward the exterior of the first body 241, is electrically connected to the first circuit board 111. The first circuit board 111 is fixed to the housing 180. Thus, the first connecting member 210 can be fixed to the housing 180 via the first circuit board 111. One end of the second connecting section 2522 of the second connecting member 220, extending toward the exterior of the second body 251, is electrically connected to the fingerprint sensor 130C. When the input device 120 is rotated, the input device 120 drives the fingerprint sensor 130C and the second connecting member 220 to rotate. The second connecting member 220 rotates axially relative to the first connecting member 210. The second metal member 252 of the second connecting member 220 is in constant contact with the first metal member 242 of the first connecting member 210, maintaining the electrical connection between the second connecting member 220 and the first connecting member 210, and thus the electrical connection between the fingerprint sensor 130C and the first circuit board 111.

[0328] In some embodiments, the main body 101 also includes a second circuit board 112 (which may be called a small board) electrically connected to the fingerprint sensor 130C, and one end of the second metal member 252 of the second connecting member 220 extending out of the second body 251 is electrically connected to the second circuit board 112 so as to be electrically connected to the fingerprint sensor 130C through the second circuit board 112.

[0329] In other embodiments, the main body 101 also includes a third circuit board 113 (also referred to as a small board) electrically connected to the first circuit board 111, and one end of the first metal member 242 of the first connecting member 210 extending out of the first body 241 is electrically connected to the third circuit board 113 so as to be electrically connected to the first circuit board 111 through the third circuit board 113.

[0330] In this embodiment, the connector 200 is disposed on the rod portion 122 and includes a first connector 210 and a second connector 220 that are coaxially arranged and rotatably connected along the circumferential direction to maintain electrical connection. The second connector 220 and the first connector 210 can always maintain contact to achieve electrical connection. One of the second connector 220 and the first connector 210 can be electrically connected to the fingerprint sensor 130C and can rotate, while the other can be electrically connected to the first circuit board 111 (or mainboard) within the housing 180 and cannot rotate. The electrical connection between the fingerprint sensor 130C and the first circuit board 111 can be established during the rotation of the fingerprint sensor 130C. Since the connector 200 is disposed entirely on the rod portion 122, it does not occupy space within the housing 180 and has better reliability. However, since the connector 200 includes a second connector 220 and a first connector 210, there are certain requirements for the radial dimension of the rod portion 122, which needs to be designed to be relatively large. Moreover, in order to ensure better contact between the second connector 220 and the first connector 210, the length of the connector 200 will be designed to be relatively long, so that the axial dimension of the rod portion 122 is relatively large.

[0331] As the rotatable input device 120, the wearable device 100 may be equipped with a sensor to identify the rotation of the input device 120. In some embodiments, the cavity in the second connector 220 may accommodate a sensor for identifying rotation (referred to as sensor 1301). Figure 20 One end of the sensor 1301 is fixedly connected to the first circuit board 111, extending toward the second connector 220 and into the cavity 2501 of the second connector 220. When the input device 120 is rotated, the sensor 1301 located in the cavity 2501 of the second connector 220 can identify the rotation or movement of the input device 120 based on relevant feature points. The specific method and structure for identifying rotation or movement can be found in the relevant description below.

[0332] In the embodiment of the present application, the fingerprint sensor 130C can be combined with other components to form a fingerprint module for fingerprint recognition. For example, the fingerprint sensor 130C can be combined with the second circuit board 112 to form a fingerprint module. It will be understood that the structure of the fingerprint module including the fingerprint sensor in the above example is only for illustrative purposes. When the fingerprint module includes a fingerprint sensor, more or fewer components may be included. The explanation of the fingerprint module below is the same as here, and unless otherwise specified, it will not be repeated later.

[0333] In some embodiments, regardless of whether the input device 120 is rotated, the fingerprint sensor 130C does not rotate, especially when the input device 120 is rotating. The connector 200 serves as a bridge connecting the first circuit board 111 (or mainboard or processor) and the fingerprint sensor 130C. When the first circuit board 111 and the fingerprint sensor 130C do not rotate, the connector 200 does not rotate either. With this structure of the wearable device 100, since the fingerprint sensor 130C does not rotate, it is easier to implement the fingerprint recognition function. Moreover, since the connector 200 does not rotate, the reliability of the connector 200 can be guaranteed as much as possible.

[0334] Figure 21 is a schematic exploded view of the connector 200 provided in an embodiment of the present application, Figure 22 The embodiment of the present application provides an installation having Figure 21 A schematic exploded view of the wearable device 100 showing the connector 200 is shown. Figure 23 The embodiment of the present application provides an installation having Figure 21 A schematic assembly diagram of a partial area of ​​the wearable device 100 showing the connector 200 is shown.

[0335] refer to Figure 21 Exemplarily, the connector 200 includes a fixing rod 260 and a plurality of metal strips 270 inserted and fixed in the fixing rod 260, and the fixing rod 260 is provided with a through hole 2601 for inserting the metal strips 270. The end of the metal strip 270 away from the fingerprint sensor can be electrically connected to the first circuit board, and the end of the metal strip 270 close to the fingerprint sensor is used to be electrically connected to the fingerprint sensor. In some embodiments, the metal strip 270 can be electrically connected to the first circuit board and the fingerprint sensor by connecting the two ends of the metal strip 270 respectively through socket welding or patch welding. In other embodiments, the metal strip 270 can be called a metal pin, and the metal pin can be split, that is, one part of the metal pin is a pin and the other part is a socket, wherein the pin and the socket can be connected to the fingerprint sensor and the first circuit board respectively.

[0336] refer to Figure 22 and Figure 23 The main body 101 of the wearable device 100 includes a housing 180 , a first circuit board 111 , a connector 200 , a fingerprint sensor 130C, and an input device 120 .

[0337] The fingerprint sensor 130C is mounted on the head portion 121 of the input device 120. A gap 120-1 exists between the fingerprint sensor 130C and the inner wall of the head portion 121, preventing contact. This prevents the fingerprint sensor 130C from rotating when the input device 120 rotates. The connector 200 is internally mounted on the rod portion 122 of the input device 120. A gap 120-1 exists between the fixing rod 260 of the connector 200 and the rod portion 122, preventing contact. This prevents the connector 200 from rotating when the input device rotates. The end of the metal strip 270 of the connector 200, facing away from the fingerprint sensor 130C, is electrically connected to the first circuit board 111. The first circuit board 191 is secured to the housing 180 of the wearable device. This allows the connector 200 to be secured to the housing via the first circuit board 111. The end of the metal strip 270, facing away from the fingerprint sensor 130C, is electrically connected to the fingerprint sensor 130C. Thus, the electrical connection between the fingerprint sensor 130C and the first circuit board 111 is achieved through the connector 200. When the input device 120 is rotated, the fingerprint sensor 130C and the component fixedly connected to the fingerprint sensor 130C (for example, the second circuit board 112 hereinafter) have a gap 120-1 with the head 121 and are not in contact, and the connector 200 and the rod 122 have a gap 120-1 and are not in contact, so the fingerprint sensor 130C and the connector 200 can be prevented from rotating.

[0338] In some embodiments, the main body 101 further includes a cover plate 1211 fixed to the end of the head 121, which is configured to contact a finger to protect components disposed within the head 121 (e.g., the fingerprint sensor 130C). For example, in an embodiment where the fingerprint sensor 130C is an optical fingerprint sensor, the cover plate 1211 can be understood as a channel disposed in the head 121 and made of a transparent material. For example, the cover plate 1211 can be a transparent glass cover plate. It is understood that in an embodiment where the cover plate 1211 is fixed to the head 121, a gap 120-1 exists between the fingerprint sensor 130C and both the head 121 and the cover plate 1211.

[0339] In other embodiments, the main body 101 also includes a second circuit board 112 (which may be called a small board) electrically connected to the fingerprint sensor 130C, and one end of the metal strip 270 close to the fingerprint sensor 130C is electrically connected to the second circuit board 112 so as to be electrically connected to the fingerprint sensor 130C through the second circuit board 112.

[0340] In other embodiments, the main body 101 also includes a third circuit board 113 (also referred to as a small board) electrically connected to the first circuit board 111, and the end of the metal strip 270 away from the fingerprint sensor 130C is electrically connected to the third circuit board 113 so as to be electrically connected to the first circuit board 111 through the third circuit board 113.

[0341] As the rotatable input device 120, the wearable device 100 may have a built-in sensor to identify the rotation of the input device 120. In some embodiments, the fixed rod 260 may contain a sensor for identifying rotation (referred to as sensor 1301).

[0342] For example, refer to Figure 21 The fixing rod 260 is provided with an opening groove 2602 which penetrates in the axial direction and opens on the outer wall 2603 of the fixing rod 260. Figure 22 and Figure 23 One end of the sensor 1301 is electrically connected to the first circuit board 111. For example, one end of the sensor 1301 can be electrically connected to the first circuit board 111 via the third circuit board 113. The sensor 1301 extends toward the fixing rod 260 and into the open slot 2602 on the fixing rod 260. In this way, when the input device 120 is rotated, the sensor 1301 located within the open slot 2602 of the fixing rod 260 can identify the rotation of the input device 120 through relevant feature points. For the specific method and structure for identifying rotation, please refer to the relevant description below.

[0343] It should be understood that Figures 1 to 23 The embodiment in which the fingerprint sensor 130C is arranged in the head 121 is only for illustrative purposes. In other embodiments, the fingerprint sensor 130C may also be arranged in the rod 122 (not shown in the figure), and the channel extends from the outer surface of the head 121 to the fingerprint sensor 130C. In one example, the fingerprint sensor 130C can be connected to the processor 110 through the connector 200, at least part of the connector 200 is arranged in the rod 122, and the connector 200 is located between the processor 110 (or the first circuit board 111) and the fingerprint sensor 130C. The connection relationship between the connector 200, the processor 110 and the fingerprint sensor 130C can be referred to. Figure 11 、 Figure 19 and Figure 23 The connection relationship shown is different in that Figure 11 、 Figure 19 and Figure 23 The fingerprint sensor 130C is disposed in the rod portion 122. In another example, the fingerprint sensor 130C may not be connected to the processor 110 through the connector 200. For example, Figure 19 If a third circuit board (small board) 113 fixed on the shell 180 is provided at the end of the rod 122 away from the head 121, and the fingerprint sensor 130 is provided in the rod 122 and fixed on the third circuit board 113, then the fingerprint sensor 130C can be connected to the first circuit board 111 through the third circuit board 113 to achieve connection with the processor 110.

[0344] In an embodiment where the input device 120 is a key or a button with a press function and the fingerprint sensor 130C is arranged on the head 121 of the input device 120, while fingerprint recognition can be realized, in order to enable mobile input such as translation or tilt of the input device 120, a switch device is provided between the circuit board and the rod 122 of the input device 120. A metal spring can be provided in the switch device to make the switch device elastic. In this way, when the input device 120 is pressed, the rod 122 contacts the switch device and presses the switch device to realize the switching function.

[0345] For ease of description, Figures 12 to 20 Taking the structure of the corresponding connector 200 as an example, the relationship between the switch device and other components in an embodiment where the input device 120 is a key or a button with a pressing function and the fingerprint sensor 130C is disposed on the head 121 of the input device 120 is described. It is understood that the switch device of the embodiment of the present application is also applicable to structures shown or not shown in other figures.

[0346] refer to Figure 24 and Figure 25 A switch device 400 is provided between the first circuit board 111 and the rod portion 122. The switch device 400 is electrically connected to the first circuit board 111. For example, in an embodiment where the wearable device 100 includes a third circuit board 113, the switch device 400 can be directly mounted on the third circuit board 113. Since a connector 200 is provided in the rod portion 122, the switch device 400 is provided adjacent to the inner end surface of the rod portion 122. The inner end surface is the end surface of the rod portion 122 away from the head portion 121, and the inner end surface is the area in contact with the switch device 400, so as to facilitate pressing the input device 120 to realize the user's mobile input. Figure 25 (Can be used with Figure 20 In contrast, the switch device 400 is directly mounted on the third circuit board 113 and is opposite to the inner end surface of the rod 122. When the input device 120 is pressed, the inner end surface of the rod 122 contacts the switch device 400, pressing the switch device 400 to realize the switching function.

[0347] It should be understood that the switch device 400 can have any structure as long as it contacts the inner end surface of the rod portion 122 .

[0348] In some embodiments, reference Figure 26 and Figure 27The switch device 400 can be generally annular in structure, and the hollow area of ​​the annular structure is used to avoid the connector 200. When the input device 120 is pressed, the inner end surface of the rod 122 contacts the switch device 400 over a large area. In this way, the force applied to the input device 120 is relatively uniform, which not only improves the stability of the pressing operation of the input device 120, but also makes the hand feel easy to control and does not easily produce a feeling of local force, which can greatly improve the user experience. It can be understood that the annular structure of the switch device 400 can be as follows Figure 26 The closed annular structure shown may also be a semi-closed annular structure (not shown in the figure), and this embodiment of the application does not impose any limitation thereto.

[0349] In other embodiments, the switch device 400 may also be in the shape of a strip, and the switch device 400 is disposed adjacent to the inner end surface of the rod portion 122. The wearable device may be provided with multiple switch devices 400, spaced apart along the inner end surface of the rod portion 122 (not shown in the figure). For example, the multiple switch devices 400 may be symmetrically and evenly arranged, so that the force applied to the input device 120 is relatively uniform. For example, the multiple switch devices 400 may include two switch devices 400, and the two switch devices 400 are symmetrically arranged. For another example, the multiple switch devices 400 are arranged in a circle along the inner end surface of the rod portion 122, forming a ring structure.

[0350] The above describes in detail the structure of the fingerprint sensor 130C provided on the input device 120 . The following describes in detail the structure of the fingerprint sensor 130C provided in the housing 180 .

[0351] In an embodiment where the fingerprint sensor 130C is disposed on the housing 180 , when a finger touches the head 121 of the input device 120 , the fingerprint sensor 130C can obtain fingerprint information based on a signal from the head 121 to perform fingerprint recognition.

[0352] As previously mentioned, the fingerprint sensor 130C of the embodiment of the present application can be an optical fingerprint sensor. In this embodiment, a channel for transmitting light is formed on the input device 120. The channel runs through the input device 120 to transmit light between the fingerprint sensor 130C and the head 121. In addition, a lens group can be provided in the input device 120 to facilitate better transmission of light reflected from the finger to the fingerprint sensor 130C. It is understood that the lens group includes one or more lenses, and the transparent group can be provided on the head 121 or the rod 122, or on both the head 121 and the rod 122.

[0353] In some embodiments, reference Figure 28The main body 101 of the wearable device 100 includes a housing 180, a cover 114, an input device 120, and a fingerprint sensor 130C. The cover 114 is connected to the top of the housing 180 and forms the surface of the main body 101. In some embodiments, the cover 114 can be a display screen 140. The housing 180 is provided with a mounting hole 181. The input device 120 includes a head 121 and a rod 122. The head 121 extends outward from the housing 180, and the rod 122 is mounted in the mounting hole 181.

[0354] Continue to refer Figure 28 The input device 120 is formed with a channel for transmitting light, which extends from the outer surface of the head 121 to the inner end surface 122-A of the rod 122 to transmit light between the fingerprint sensor 130C and the head 121. The inner end surface 122-A of the rod 122 is an end surface perpendicular to the axial direction (e.g., the x direction) of the rod 122 and away from the head 121. The outer surface of the head 121 includes the outer end surface 121-A and the side surface 121-B of the head 121. In some embodiments, reference Figure 28 The shaft portion 122 is provided with a first channel 1231 extending axially through the shaft portion 122. The head portion 121 is made of a transparent material capable of transmitting light. The transparent head portion 121 and the first channel 1231 of the shaft portion 122 form a channel for transmitting light between the surface of the head portion 121 and the fingerprint sensor 130C. The first channel 1231 can be a cavity extending axially through the shaft portion 122, or a transparent structure filled with a transparent material, which is not limited in this embodiment of the present application.

[0355] Continue to refer Figure 28 A lens group is provided in the first channel 1231 of the rod portion 122, and the lens group includes one or more lenses 310. Figure 28 A lens 310 is shown in the figure, which is used to collect light reflected by the finger. The reflected light is transmitted to the fingerprint sensor 130C to form fingerprint information for fingerprint recognition.

[0356] In order to better transmit light, illustratively, the first channel 1231 provided on the rod portion 122 is arranged opposite to the fingerprint sensor 130C.

[0357] In some embodiments, the focal length of the lens 310 may be smaller than the distance between the fingerprint sensor 130C and the lens 310, and the optical path formed is as follows: Figure 28 In other embodiments, the focal length of the lens 310 is greater than the distance between the fingerprint sensor 130C and the lens 310, and the optical path formed is as follows: Figure 29 When the lens group includes a plurality of lenses 310 , the focal lengths of any two lenses 310 may be the same or different.

[0358] The lens 310 may be a convex lens.

[0359] refer to Figure 30 , the lens 310 may be a single convex lens (such as Figure 30 (a) and (b) in the figure), or a biconvex lens (such as Figure 30 (c)) or rectangular convex lens (such as Figure 30 (d)) in the present application does not impose any limitation on this.

[0360] The surface of the lens 310 can be spherical or aspherical, and the curvatures of the biconvex lens or rectangular convex lens can be the same or different, which is not limited in the present embodiment. When the lens group includes multiple lenses 310, the shapes of any two lenses 310 can be the same or different.

[0361] The channels in the input device 120 of the embodiment of the present application can not only be Figure 28 As shown, other structures are also possible.

[0362] refer to Figure 31 A transparent cover plate 1211 is provided on the outer end surface 121-A of the head portion 121. A second channel 1232 is provided on the head portion 121, and a first channel 1231 is provided on the stem portion 122. One end of the second channel 1232 is connected to the first channel 1231, and the other end is connected to the cover plate 1211. Thus, the transparent cover plate 1211, the second channel 1232, and the first channel 1231 form a channel for transmitting light between the surface of the head portion 121 and the fingerprint sensor 130C. The first channel 1231 can be a cavity extending through the stem portion 122 along the axial direction (e.g., the x-direction) of the stem portion 122, or a transparent structure formed by filling the cavity with a transparent material. Similarly, the second channel 1232 can be a cavity formed in the head portion 121, or a transparent structure formed by filling the cavity with a transparent material. It should be understood that this embodiment is also well-suited for structures where the head portion 121 is made of a non-transparent material.

[0363] In the wearable device provided by the above embodiment, the fingerprint sensor 130C is arranged in the housing 180 and can be electrically connected to the mainboard in a simple manner. There is no need to use a connector or other components in the input device 120 to realize an electrical connection between the mainboard and the fingerprint sensor 130C, so that the reliability of fingerprint recognition can be achieved, especially when the input device 120 is rotated. A channel for transmitting light is provided in the input device 120, and a lens group that can converge light is provided in the first channel in the rod 122. When fingerprints can be recognized, the space of the rod 122 is effectively utilized, and the volume of the wearable device will not be greatly increased, so that a miniaturized design of the wearable device can be achieved. In addition, by arranging the lens group in the rod 122, it is easy to replace the head 121, which increases the scalability of the wearable device.

[0364] Next, other possible designs of the lens group in the input device 120 are described. Figure 32 and Figure 33 The structure shown is that the transparent group is located at the head 121. Figure 34 and Figure 35 The structure shown is that the lens group is located on the head portion 121 and the rod portion 122.

[0365] In other embodiments, reference Figure 32 , Figure 32 Can be used with Figure 28 For comparison, Figure 32 and Figure 28 The biggest difference is that the lens group is set in the head 121. The head 121 is made of transparent material, and a second channel 1232 is set in the head 121, which is connected to the first channel 1231 in the rod 122. A lens group is set in the second channel 1232, which includes one or more lenses 310 ( Figure 32 A lens 310 is shown in FIG. 3 ) for converging light reflected from the finger, and transmitting the reflected light to the fingerprint sensor 130C to form fingerprint information for fingerprint detection. For other descriptions of the lens group, please refer to Figure 28 and Figure 29 The first channel 1231 can be a cavity formed in the rod portion 122, or a transparent structure formed by filling the cavity with a transparent material. Similarly, the second channel 1232 can be a cavity formed in the head portion 121, or a transparent structure formed by filling the cavity with a transparent material. However, in order to install the transparent group, an empty area for installing the lens group needs to be reserved in the transparent structure.

[0366] In other embodiments, reference Figure 33 , Figure 33 Can be used with Figure 31 For comparison, Figure 33 and Figure 31The biggest difference is that the lens group is set in the head 121. A transparent cover plate 1211 is set on the outer end surface 121-A of the head 121, a second channel 1232 is set on the head 121, and a first channel 1231 is set on the rod 122. One end of the second channel 1232 is connected to the first channel 1232, and the other end is connected to the cover plate 1211. Among them, a lens group is set in the second channel 1232 of the head 121, and the lens group includes one or more lenses 310 ( Figure 33 A lens 310 is shown in FIG. 3 ) for converging light reflected from the finger, and transmitting the reflected light to the fingerprint sensor 130C to form fingerprint information for fingerprint detection. For other descriptions of the first channel 1231, the second channel 1232 and the lens group, please refer to Figure 31 The relevant description will not be repeated here.

[0367] The wearable device provided by the above embodiment can not only realize the miniaturization of the wearable device and improve the rotation stability of the input device, but also, since the radial dimension of the head 121 is larger than the radial dimension of the rod 122, compared with the structure in which the lens group is set in the rod 122, setting the lens group in the larger head 121 can simplify the design difficulty and cost of the lens group.

[0368] In other embodiments, reference Figure 34 , Figure 34 Can be used with Figure 28 For comparison, Figure 34 and Figure 28 The biggest difference is that the lens group is arranged in the head 121 and the rod 122. The head 121 is made of a transparent material, and a second channel 1232 is provided in the head 121, which communicates with the first channel 1231 in the rod 122. A part of the lens group is provided in the first channel 1231, and another part of the lens group is provided in the second channel 1232. Among them, one or more lenses 310 are provided in the first channel 1231, and the lenses 310 in the first channel 1231 are convex lenses. One or more lenses 310 are provided in the second channel 1232, and the lenses 310 in the second channel 1232 are concave lenses. For example, Figure 34 The first channel 1231 and the second channel 1232 are shown as a lens 310. The description of the first channel 1231 and the second channel 1232 can be referred to. Figure 32 The relevant description will not be repeated here.

[0369] For example, the lens 310 of the first channel 1231 is a convex lens, and the lens 310 of the second channel 1232 is a concave lens. The concave lens is used to collect a wider range of light reflected by the finger, and the convex lens and the concave lens are used together to converge the light reflected by the finger. For a description of the convex lens, please refer to Figure 30 The relevant description is omitted here. Figure 35 , the concave lens can be a single concave lens (such as Figure 35 (a) or (b) in the figure), the concave lens can also be a double concave lens (as shown in Figure 35 As shown in (c) in FIG), when the concave lens is a biconcave lens, the curvatures of the two concave surfaces may be the same or different. In addition, when the lens group includes multiple concave lenses, the focal lengths of any two concave lenses may be the same or different.

[0370] In other embodiments, reference Figure 36 , Figure 36 Can be used with Figure 31 For comparison, Figure 36 and Figure 31 The biggest difference is that the lens group is arranged on the head 121 and the rod 122. A transparent cover 1211 is provided on the outer end surface 121-A of the head 121, a second channel 1232 is provided on the head 121, and a first channel 1231 is provided on the rod 122. One end of the second channel 1232 is connected to the first channel 1232, and the other end is connected to the cover 1211. A part of the lenses 310 of the lens group is arranged in the first channel 1231, and the other part of the lenses 310 of the lens group is arranged in the second channel 1232. Among them, one or more lenses 310 are provided in the first channel 1231, and the lenses 310 of the first channel 1231 are convex lenses. One or more lenses 310 are provided in the second channel 1232, and the lenses 310 of the second channel 1232 are concave lenses. For example, Figure 36 A convex lens and a concave lens are shown. The description of the first channel 1231 and the second channel 1232 can be referred to Figure 32 For the description of the lens group, please refer to Figure 34 and Figure 35 The relevant description will not be repeated here.

[0371] The wearable device provided by the above embodiment can not only realize the miniaturization of the wearable device and improve the rotation stability of the input device, but also, by arranging the lens group on the rod 122 and the head 121, while maximizing the use of the space of the input device, the concave lens arranged on the head 121 can further increase the light passing through the input device and increase the light energy, thereby improving the efficiency of fingerprint recognition.

[0372] The sidewalls of the channel in the embodiment of the present application may be made of light-absorbing material or diffusely reflecting material to absorb light reflected from the sidewalls, allowing parallel light to pass through the channel as much as possible, thereby reducing the impact of other stray light on the efficiency of fingerprint recognition.

[0373] In embodiments where the first channel 1231 is provided within the shaft portion 122, the sidewalls forming the first channel 1231 may, for example, be made of a light-absorbing material or a diffusely reflective material. In embodiments where the second channel 1232 is provided within the head portion 121, the sidewalls forming the second channel 1232 may, for example, be made of a light-absorbing material or a diffusely reflective material. In embodiments where the cover plate 1211 is provided within the head portion 121, the sidewalls of the cover plate 1211 may, for example, be made of a light-absorbing material or a diffusely reflective material. In embodiments where the head portion 121 is made of a transparent material, the circumferential inner wall of the head portion 121 may be made of a light-absorbing material or a diffusely reflective material.

[0374] As previously mentioned, in the embodiments of the present application, fingerprint sensor 130C can be combined with other components to form a fingerprint module for fingerprint recognition. For example, in embodiments where fingerprint sensor 130C is an optical fingerprint sensor and is disposed within housing 180, fingerprint sensor 130C and a lens assembly can form a fingerprint module. Furthermore, in embodiments where the optical fingerprint sensor does not include a light-emitting unit, fingerprint sensor 130C, a lens assembly, and a light-emitting unit can form a fingerprint module.

[0375] In the above Figures 28 to 36 In the corresponding embodiment, a lens group is provided in the input device. It should be understood that the input device does not need to be provided with a lens. It is only necessary to form a channel for transmitting light in the input device. The channel reference Figures 28 to 36 The structural settings shown are not repeated here.

[0376] Figures 28 to 36 The embodiment shown is one in which light is transmitted from the axial end of the head 121 (or, from the end surface 121-A of the head 121). It will be understood that light can also be transmitted through the circumferential end of the head 121 (or, from the side surface 121-B of the head 121).

[0377] For example, taking the fingerprint sensor 130C as an example, Figure 37 and Figure 38The lens assembly includes one or more lenses 310, a first channel 1231 disposed within the stem 122 of the input device 120, and a transparent cover 1211 in an annular structure. Cover 1211 is disposed at an end of the circumferential direction of the head 121, surrounds the circumference of the head 121, and is fixedly connected to the housing of the head 121. For example, cover 1211 surrounds the circumference of the head 121. The cavity within the annular structure of cover 1211 forms a second channel 1232. A reflector 710 is fixedly disposed within the second channel 1232, allowing light to enter the lens 310 through the reflector 710. The reflective device 710 has a reflective surface 711, and the second channel 1232 is connected to the first channel 1231. In this way, light passes through the cover 1211 and the second channel 1232 to reach the reflective device 710, is reflected by the reflective surface 711 of the reflective device 710, and the reflected light enters the lens 310 through the first channel 1231 to reach the fingerprint sensor 130C, so that the fingerprint recognition is performed by the fingerprint sensor 130C. It can be understood that the reflective device 710 can receive light at a certain angle and realize light entering within the angle range. For example, Figure 37 and Figure 38 As shown, the reflective device 710 can receive light at an angle of 360 degrees.

[0378] When light is transmitted through the outer end of the head 121 in the circumferential direction, the user can press a finger on the circumferential end of the head 121 (for example, on the cover 1211 of the head 121). For example, the user can slide or roll on the circumferential end of the head 121 to perform fingerprint recognition. The circumferential end of the head 121 can be the end of a transparent head 121 or the end of a transparent cover 1211, and this embodiment of the application does not impose any limitation.

[0379] In an embodiment where the fingerprint sensor 130C is an optical sensor and light is transmitted through the end portion of the head portion 121 in the circumferential direction (e.g., Figure 37 and Figure 38As shown in FIG1 , a finger contacts the circumferential end of the head 121. As the circumferential end of the head 121 rolls, light reflected by the finger enters the input device 120 through the circumferential end of the head 121 and reaches the fingerprint sensor 130C. When the area of ​​the channel for transmitting light in the head 121 (for example, the area of ​​the cover 1211 or the area of ​​the transparent surface of the head 121 in the circumferential direction) is larger than the area of ​​the region where the finger contacts the head 121 in a single time, when the finger presses on the circumferential end of the head 121, the fingerprint sensor 130C can detect not only the fingerprint information of the region contacted by the finger (referred to as the contact area), but also the fingerprint information of the adjacent region connected to the contact area. In other words, when the finger contacts the circumferential end of the head 121 in a single time, fingerprint information of multiple regions including the contact area can be detected. It can be understood that the adjacent region connected to the contact area belongs to the region of the channel in the circumferential direction.

[0380] In the embodiments of the present application, a single finger contact with the head 121 refers to a finger contacting the head 121 at a certain time without rolling the head 121, and a single contact with the head 121 has only one contact area. Similarly, multiple finger contact with the head 121 refers to a finger contacting the head 121 at multiple times while rolling on the head 121, and multiple contact areas may be generated at each time.

[0381] In some scenarios, the outer surface area of ​​the head 121 of the input device 120 is relatively small (for example, the input device 120 is a crown), which may result in a smaller area of ​​contact between the finger and the head 121, which is not conducive to fingerprint recognition. Therefore, in an embodiment of the present application, the fingerprint information of multiple continuous areas detected each time the finger contacts the head 121 during the process of rolling the finger in the circumferential direction of the end of the head 121 can be used to perform fingerprint recognition based on the fingerprint information detected multiple times.

[0382] In the embodiment of the present application, the area where the fingerprint sensor 130C can detect fingerprint information when the finger contacts the head 121 once is recorded as a fingerprint area, which includes the contact area and one or more areas connected to the contact area.

[0383] In one example, the fingerprint area detected by the fingerprint sensor 130C includes the contact area and an area connected to the contact area, which may be an area on either side of the contact area.

[0384] In another example, the fingerprint area detected by the fingerprint sensor 130C includes a contact area and two areas connected to the contact area, and the two areas are divided into two areas located on both sides of the contact.

[0385] Figure 391 is a schematic diagram of multiple areas that can be detected when a finger contacts the head 121 according to an embodiment of the present application. Figure 39 The circumferential end of the head 121 is provided with a transparent cover 1211 surrounding the head 121, forming an end including the cover 121. The cover 1211 can be understood as a part of the channel of the head 121. The cover 1211 surrounds the head 121, which means that the finger 10 can roll one circle (360 degrees) on the head 121. If it is assumed that the fingerprint recognition process requires the finger 10 to roll one circle on the head 121 before fingerprint recognition can be performed, then one circle of the cover 121 is the total area that the finger 10 and the cover 1211 can contact during the fingerprint recognition process.

[0386] When finger 10 rolls in contact with cover 1211, at a certain point in time, area S1 is the area of ​​head 121 where finger 10 actually touches the area. Areas S0 and S2 are either or both areas that finger 10 does not touch but can detect, and areas S0 and S2 are areas connected to area S1. In one example, the fingerprint area detectable by fingerprint sensor 130C includes contact area S1 and either area S0 or area S2. In another example, the fingerprint area detectable by fingerprint sensor 130C includes contact area S1, area S0, and area S2.

[0387] In the embodiment of the present application, the finger may contact different areas of the head 121 multiple times during the rolling process at the end of the head 121 in the circumferential direction. During each contact, the fingerprint sensor 130C may detect fingerprint information of multiple areas. Therefore, in some embodiments, the fingerprint information of multiple areas obtained by the finger contacting the head 121 multiple times in a row can be fused, and the fingerprint can be identified based on the fused fingerprint information.

[0388] Below, Figure 39 Taking the head 121 and the finger rolling on the head 121 as an example, the method of fingerprint recognition through fingerprint information of multiple areas is explained. In addition, assuming that the finger 10 slides and rolls from bottom to top, when the finger 10 touches the head 121 once, the fingerprint sensor 130C can detect the fingerprint information of the contact area and the two areas connected to the contact area.

[0389] 1. Finger 10 contacts cover 1211 at a first time (denoted as time T0). The fingerprint area detected by fingerprint sensor 130C at time T0 is denoted as fingerprint area S-T0. Fingerprint area S-T0 includes contact area S1-T0 and areas S0-T0 and S2-T0 on both sides of contact area S1-T0. Fingerprint sensor 130C obtains fingerprint information based on fingerprint area S-T0. Exemplarily, the fingerprint information includes a graphic feature sequence I-T0 for representing fingerprint features. Graphic feature sequence I-T0 includes graphic feature sequence I-S0-T0, graphic feature sequence I-S1-T0, and graphic feature sequence I-S2-T0. Graphic feature sequence I-S0-T0 represents the fingerprint information of area S0-T0, graphic feature sequence I-S1-T0 represents the fingerprint information of area S1-T0, and graphic feature sequence I-S2-T0 represents the fingerprint information of area S2-T0.

[0390] For example, the fingerprint sensor 130C can distinguish the boundary between area S0 and area S1 and the boundary between area S2 and area S1 based on the light intensity. Based on the boundary between S0 and S1 and the boundary between S2 and S1, the fingerprint information of each area can be better obtained.

[0391] 2. Finger 10 contacts cover 1211 at a second time (denoted as time T1). The fingerprint area detected by fingerprint sensor 130C at time T1 is denoted as fingerprint area S-T1. Fingerprint area S-T1 includes contact area S1-T1 and areas S0-T1 and S2-T1 on both sides of contact area S1-T1. Fingerprint sensor 130C obtains fingerprint information based on fingerprint area S-T1. Exemplarily, the fingerprint information includes a graphic feature sequence I-T1 for representing fingerprint features. Graphic feature sequence I-T1 includes graphic feature sequence I-S0-T1, graphic feature sequence I-S1-T1, and graphic feature sequence I-S2-T1. I-S0-T1 represents the fingerprint information of area S0-T1, I-S1-T1 represents the fingerprint information of area S1-T1, and I-S2-T1 represents the fingerprint information of area S2-T1.

[0392] 3. The wearable device 100 (for example, a sensor for identifying rotation) detects the angular velocity ω of the rotation of the input device 120, and calculates the intersection area of ​​the fingerprint area S-T0 detected at the first time T0 and the fingerprint area S-T1 detected at the second time T1 based on the radius R of the head 121 and the time difference T1-T0 between the first time T0 and the second time T1, and fuses the fingerprint information of the intersection area. For example, the fingerprint information is de-overlapped and denoised to obtain new fingerprint information. Assume that the area S2-T0 at the first time T0 overlaps with the area S1-T1 at the second time T1, then the graphic feature sequence I-S2-T0 corresponding to the area S2-T0 overlaps with the graphic feature sequence I-S1-T1 corresponding to the area S1-T1. The new fingerprint information is formed after de-overlapping and denoising the fingerprint information, and the graphic feature sequence in the new fingerprint information is recorded as I-T0T1. I-T0T1 includes I-S0-T0, I-S1-T0, I-S2-T0 and I-S2-T1, that is, I-T0T1=I-S0-T0+I-S1-T0+I-S2-T0+I-S2-T1.

[0393] 4. Following steps 1-3 above, the fingerprint information of the third time, the fourth time, and so on, is obtained. After the user completes a complete roll, a new fingerprint information is finally obtained. The complete roll here means that the head 121 needs to be rolled according to a preset angle during the fingerprint recognition process.

[0394] 5. Compare the final fingerprint information with the pre-stored fingerprint information to perform fingerprint recognition. For example, if the similarity of the two fingerprint information meets the preset conditions, the fingerprint recognition is successful; if the similarity of the two fingerprint information does not meet the preset conditions, the fingerprint recognition is unsuccessful.

[0395] In the process of pre-storing the user's fingerprint information, the above steps 1-4 can be executed to complete a scrolling process and obtain fingerprint information. In order to improve the reliability of the fingerprint information, the above steps 1-4 can be repeated twice to obtain fingerprint information. The fingerprint information obtained twice is compared. After the similarity of the fingerprint information obtained twice meets the preset conditions, the fingerprint information is entered into the wearable device to realize the entry and pre-storage of fingerprint information.

[0396] In the prior art, fingerprint collection and recognition are all performed in a fixed area that is in contact with the finger. When the user's finger rolls or slides in this area, the sensor does not know how the user's finger rolls or slides, and can only rely on default rules (from top to bottom, or from left to right), or use image recognition splicing, which results in low collection efficiency and low recognition efficiency. In the embodiment of the present application, when the finger touches the head once, the fingerprint sensor can simultaneously detect fingerprint information in the contact area and the non-contact area, and process the multiple fingerprint information obtained from the previous contact and the fingerprint information obtained from the next contact to perform fingerprint recognition. This eliminates the need to know the finger's operating rules, and can increase the fingerprint collection area to improve fingerprint recognition efficiency. This is particularly suitable for smaller structures of the input device 120.

[0397] Below, Figures 40 to 45 As an example, a graphical user interface (GUI) provided by an embodiment of the present application during the rolling process of the finger on the head 121 is introduced.

[0398] Figures 40 to 43 Provided are a set of schematic diagrams of GUI changes of the wearable device 100 when a user rolls a fingerprint with a single finger in an embodiment of the present application.

[0399] See also Figures 40 to 43 As shown in (a), the GUI is when the wearable device 100 is in a screen-off or screen-locked state.

[0400] When the user presses a single finger on the area where the fingerprint sensor 130C detects the fingerprint on the side 121-B of the head 121, the fingerprint sensor 130C set in the input device 120 is triggered to capture the user's fingerprint information. The user's fingerprint information can be transmitted to the fingerprint sensor 130C through the cover 1211, the second channel 1232, and the first channel 1232 in sequence. At this time, the wearable device 100 is in a bright screen state, and the wearable device 100 can also display a fingerprint entry progress bar and related prompt information 1 about fingerprint entry on the display interface. The fingerprint entry progress bar is used to indicate the progress of the user's single-finger fingerprint entry. For details, see Figure 40 (b) Figure 41 (b) Figure 42 (b) Figure 43 As shown in (b) in .

[0401] For example, Figure 40 (b) Figure 41 (b) Figure 42 (b) Figure 43 As shown in (b), the prompt information 1 includes "fingerprint entry" and "roll the crown until the watch vibrates".

[0402] This application does not limit the shape, size, or display color of the fingerprint entry progress bar. For example, the user can set or default the shape, size, or display color of the fingerprint entry progress bar.

[0403] For example, the fingerprint entry progress bar can be presented in the form of a fingerprint icon. Figure 40 As shown in (b) in FIG, the fingerprint entry progress bar is a fingerprint icon 1.

[0404] For example, the fingerprint entry progress bar can be presented in the form of a closed graphic. Figure 41 As shown in (b) in FIG. 2 , the fingerprint entry progress bar is a rounded rectangle 2 .

[0405] For example, the fingerprint entry progress bar can be presented in the form of a screen interface of the wearable device 100. For example, Figure 42 As shown in (b) in FIG, the fingerprint entry progress bar is the screen interface 3 of the wearable device 100 .

[0406] For example, the fingerprint entry progress bar can be presented in the form of a light emitting device provided on the periphery of the main body 101 of the wearable device 100. The light emitting device 4 can include one light emitting unit or multiple light emitting units. Figure 43 As shown in (b) , the fingerprint entry progress bar is a light-emitting strip 4 provided on the periphery of the main body 101 .

[0407] The user can complete the fingerprint entry by scrolling the input device 120 with a single finger according to the prompt information 1. During the process of scrolling the input device 120 with a single finger, in addition to displaying the prompt information 1 on the display interface of the wearable device 100, the fingerprint entry progress bar on the display interface of the wearable device 100 changes in a positive correlation with the amount of single-finger fingerprint area entered by the user.

[0408] This application does not limit the form in which the fingerprint entry progress bar presents the positive correlation change.

[0409] For example, the change of the fingerprint entry progress bar is realized by the filling effect of the fingerprint icon. Figure 40 As shown in (c), the wearable device 100 can fill the corresponding area in the corresponding fingerprint icon 1 according to the area of ​​the single-finger fingerprint recorded by the user, thereby reflecting the progress of the user's single-finger fingerprint recording by the amount of the filled area of ​​the fingerprint icon 1.

[0410] This application does not limit the fill color of the fingerprint icon. For example, the user can set or default the fill color of the fingerprint icon. For example, the fill color of the fingerprint icon can be the same as the display color of the fingerprint icon, or the fill color of the fingerprint icon can be different from the display color of the fingerprint icon.

[0411] For example, the fingerprint entry progress bar is changed by filling a circular rectangle. Figure 41 As shown in (c), the wearable device 100 can fill the corresponding area in the corresponding circular rectangle 2 according to the area of ​​the single-finger fingerprint recorded by the user, so that the progress of the user's single-finger fingerprint recording can be reflected by the amount of the filled area of ​​the circular rectangle 2.

[0412] This application does not limit the fill color of the circular rectangle. For example, the user can set or default the fill color of the circular rectangle. For example, the fill color of the circular rectangle can be the same as the display color of the circular rectangle, or the fill color of the circular rectangle can be different from the display color of the circular rectangle.

[0413] For example, the change of the fingerprint entry progress bar is realized by the filling effect of the screen interface of the wearable device 100. Figure 42 As shown in (c), the wearable device 100 can fill the corresponding area in the screen interface 3 of the wearable device 100 according to the area of ​​the single-finger fingerprint recorded by the user, so that the progress of the user's single-finger fingerprint recording can be reflected by the amount of the filled area of ​​the screen interface 3 of the wearable device 100.

[0414] This application does not limit the fill color of the screen interface of the wearable device 100. For example, the user can set or default the fill color of the screen interface of the wearable device 100. For example, the fill color of the screen interface of the wearable device 100 can be the same as the display color of the screen interface of the wearable device 100, or the fill color of the screen interface of the wearable device 100 can be different from the display color of the screen interface of the wearable device 100.

[0415] For example, the change of the fingerprint recording progress bar is realized by the illuminated area of ​​the light strip 4 provided on the periphery of the main body 101. Figure 43 As shown in (c), the wearable device 100 can control the corresponding light-emitting unit to emit light according to the area of ​​the single-finger fingerprint recorded by the user, and transmit the light to the light-emitting strip 4 set on the periphery of the main body 101, so that the progress of the user's single-finger fingerprint recording is reflected by the amount of the light-emitting strip 4 set on the periphery of the main body 101 that is illuminated.

[0416] The colors of the illuminated areas of the light strip 4 can be one or more colors.

[0417] This application does not limit the color of the illuminated light strip 4. For example, the user can set or default the color of the illuminated light strip 4. For example, the color of the illuminated light strip 4 can be the same as the color displayed at the edge of the light strip 4, or the color of the illuminated light strip 4 can be different from the color displayed at the edge of the light strip 4.

[0418] In one achievable manner, while the user is scrolling the input device 120 with a single finger, the display interface of the wearable device 100 may also prompt the user with the direction of the fingerprint entry progress bar.

[0419] For example, Figure 41 As shown in (c) in FIG. 1 , an arrow 5 may also be displayed on the display interface of the wearable device 100 , and the arrow 5 is used to prompt the user that the fingerprint entry progress bar moves from top to bottom.

[0420] When the user completes the single-finger fingerprint entry, the wearable device 100 can vibrate to remind the user that a full fingerprint entry progress bar and related prompt information 2 about the completion of fingerprint entry are displayed on the display interface. Figure 40 (d) Figure 41 (d) Figure 42 (d) Figure 4 As shown in (d) in .

[0421] For example, Figure 40 (d) Figure 41 (d) Figure 42 (d) Figure 43 As shown in (d), the prompt information 1 includes "fingerprint entry" and "fingerprint entry completed".

[0422] For example, Figure 40 As shown in (d) in FIG, the display interface of the wearable device 100 displays a fully filled fingerprint icon 1 .

[0423] For example, Figure 41 As shown in (d) in FIG. 1 , a fully filled circular rectangle 2 is displayed on the display interface of the wearable device 100 .

[0424] For example, Figure 42 As shown in (d) in FIG. 1 , the display interface of the wearable device 100 displays a fully filled screen interface.

[0425] For example, Figure 43 As shown in (d) in FIG. 1 , the display interface of the wearable device 100 displays the light-emitting strip 4 that is fully lit.

[0426] The fingerprint entry process can also be the fingerprint entry process in fingerprint recognition. After the user completes the single-finger fingerprint entry, the wearable device 100 needs to identify the user's fingerprint. If the user's fingerprint is successfully identified, the interface can automatically jump to the unlocked interface of the wearable device 100. For example, Figure 40 (e) in Figure 41 (e) in Figure 42 (e) in Figure 43 As shown in (e) in FIG. 1 , it is the interface after the wearable device 100 is unlocked.

[0427] Among them, the process of the wearable device 100 identifying the recorded user's fingerprint can be specifically that the wearable device 100 matches the fingerprint recorded by the user with the fingerprint template of the owner stored in the wearable device 100. When the user's fingerprint recorded by the wearable device 100 successfully matches the fingerprint template of the owner stored in the wearable device 100, it can be considered that the wearable device 100 has successfully identified the user's fingerprint.

[0428] and Figures 40 to 43 The difference is that Figure 44 1 is a set of schematic diagrams of GUI changes of the wearable device 100 when a user uses two fingers to scroll and enter a fingerprint, as provided in an embodiment of the present application.

[0429] See also Figure 44 As shown in (a), the GUI is when the wearable device 100 is in a screen-off or screen-locked state.

[0430] When the user rotates the input device 120 with two fingers and presses the fingerprint sensor 130C on the side 121-B of the head 121 with two fingers, the fingerprint sensor 130C set in the input device 120 is triggered to capture the user's fingerprint information. At this time, the wearable device 100 is in the screen-on state, and the wearable device 100 can also display a two-finger fingerprint entry progress bar and related reminder information 3 about the two-finger fingerprint entry on the display interface, wherein the two-finger fingerprint entry progress bar is used to indicate the progress of the user's two-finger fingerprint entry.

[0431] The dual-finger fingerprint entry progress bar may include two fingerprint entry progress bars.

[0432] This application does not limit the form of the two fingerprint entry progress bars.

[0433] For example, the two-finger fingerprint recording progress bar may include two Figure 40 The fingerprint icons shown in (b) in the figure are as follows: one fingerprint icon is used to indicate the progress of fingerprint entry of one of the two fingers of the user; and the other fingerprint icon is used to indicate the progress of fingerprint entry of the other finger of the two fingers of the user.

[0434] For example, the two-finger fingerprint recording progress bar may include two Figure 41 The circular rectangles shown in (b) in FIG. 1 are used to indicate the progress of fingerprint entry of one of the two fingers of the user, and the other circular rectangle is used to indicate the progress of fingerprint entry of the other finger of the two fingers of the user.

[0435] Exemplarily, the dual-finger fingerprint recording progress bar is presented in a form where the area of ​​the two fingerprint recording progress bars added together covers the entire screen interface of the wearable device 100 .

[0436] For example, the two fingerprint entry progress bars can be distributed left and right to occupy the entire screen interface of the wearable device 100. Figure 44 As described in (b) above, the two-finger fingerprint registration progress bar includes two fingerprint registration progress bars on the left and right, and the two fingerprint registration progress bars occupy the entire screen interface of the wearable device 100. Among them, one fingerprint registration progress bar is the fingerprint registration progress bar of the user's finger 1, and the other fingerprint registration progress bar is the fingerprint registration progress bar of the user's finger 2.

[0437] Exemplarily, the two fingerprint entry progress bars may be distributed vertically to fill the entire screen interface of the wearable device 100 .

[0438] like Figure 44 As shown in (b) in FIG, prompt information 3 includes “fingerprint entry” and “roll the crown with two fingers until the watch vibrates”.

[0439] The user can complete the fingerprint entry by scrolling the input device 120 with two fingers according to the prompt 3. During the process of scrolling the input device 120 with two fingers, in addition to displaying the prompt 3 on the display interface of the wearable device 100, the dual fingerprint entry progress bar on the display interface of the wearable device 100 changes in a positive correlation with the amount of dual fingerprint area entered by the user.

[0440] This application does not limit the form in which the fingerprint entry progress bar presents the positive correlation change.

[0441] Exemplarily, the change of each fingerprint entry progress bar is realized by a filling effect of the fingerprint entry progress bar.

[0442] The filling effects of the two fingerprint entry progress bars may be the same or different, and this application does not limit this.

[0443] For example, Figure 44As shown in (c), the wearable device 100 can fill the corresponding areas in the fingerprint entry progress bar corresponding to finger 1 and finger 2 according to the areas of the two-finger fingerprints entered by the user, thereby reflecting the progress of the user's two-finger fingerprint entry through the amount of filled area of ​​each fingerprint entry progress bar in the two-finger fingerprint entry progress bar of the wearable device 100.

[0444] When the user completes the double-fingerprint entry, the wearable device 100 can vibrate to remind the user that a full double-fingerprint entry progress bar and related prompt information 2 about the completion of fingerprint entry are displayed on the display interface. Figure 44 As shown in (d), the prompt information 3 includes "fingerprint entry" and "fingerprint entry completed".

[0445] The fingerprint entry process can also be the fingerprint entry process in fingerprint recognition. After the user completes the double-finger fingerprint entry, the wearable device 100 needs to identify the user's fingerprint. If the user's fingerprint is successfully identified, the interface can be automatically jumped to the unlocked interface of the wearable device 100. For example, Figure 44 As shown in (e) in FIG. 1 , it is the interface after the wearable device 100 is unlocked.

[0446] about Figure 44 For parts not described in Figures 40 to 43 The corresponding description in is not repeated here.

[0447] When the user needs to open privacy-related content on the wearable device 100, the wearable device 100 can collect the user's fingerprint through the input device 120 to verify the user's identity.

[0448] The privacy-related content may be set by the user or by the system default of the wearable device 100 .

[0449] For example, the privacy-related content may be folders, applications, pictures, documents, etc.

[0450] Below, Figure 45 Taking the example of FIG. 1 as an example, a set of GUI change diagrams of the wearable device 100 are introduced when a user uses an application involving privacy authority or identity authentication on the wearable device 100.

[0451] See also Figure 45 As shown in (a), when a user uses a wallet application on the wearable device 100 that involves privacy authority or identity authentication, the wearable device 100 can remind the user to perform identity authentication.

[0452] For example, the wearable device 100 may display a prompt message 4 on the display interface to remind the user to authenticate. Figure 45 As shown in (b), prompt information 3 includes "security authentication" and "enter fingerprint to enter encryption application" and so on.

[0453] In one practicable manner, the wearable device 100 may also remind the user how to authenticate.

[0454] For example, Figure 45 As shown in (b) of FIG. 1 , the wearable device 100 may display a schematic diagram on the display interface showing how the user authenticates the user. The schematic diagram may include the user touching the outer end surface 121-A of the input device 120 with one finger and clicking on a corresponding application menu with another finger.

[0455] The user can complete the identity verification according to the prompt 4. For example, Figure 45 As shown in (c) in FIG. 1 , the user touches the outer end surface 121 -A of the input device 120 with the index finger, and at the same time, the user clicks the wallet menu with the thumb.

[0456] When the wearable device 100 passes the user's identity authentication, the display interface of the wearable device 100 displays an application interface related to privacy authority or identity authentication. Figure 45 As shown in (d) in FIG, the wallet application interface is displayed on the display interface of the wearable device 100.

[0457] It should be understood that Figures 1 to 45 The structures of the various components in the electronic device shown and the connection relationship between the components are only schematic illustrations, and the structure of any replaceable components that play the same role as each component is within the protection scope of the embodiments of the present application.

[0458] Above, combined Figures 4 to 45 The wearable device that realizes the fingerprint recognition function of the embodiment of the present application is described. Figures 46 to 69 , the structure of the wearable device identifying the rotation or movement of the input device in the embodiment of the present application is described.

[0459] In an embodiment of the present application, the input device 120 is used to provide user input. A sensing element may be provided in the wearable device 100. The sensing element can detect the motion state of the input device 120, such as rotation or movement, to identify the user input and respond to the user input.

[0460] The sensing element of the embodiment of the present application may include one or more sensors. The sensors may be various types of sensors. For example, the sensors may be optical sensors, capacitive sensors, magnetic sensors, pressure sensors, etc.

[0461] Hereinafter, various types of sensors included in the sensing element will be described in detail for an embodiment of recognizing user input through the sensing element. Figures 46 to 58 FIG. 1 shows a schematic structural diagram of a wearable device in which the sensing element includes an optical sensor. Figures 59 to 63 FIG. 1 shows a schematic structural diagram of a wearable device in which the sensing element includes a capacitive sensor. Figures 64 to 67 FIG. 1 shows a schematic structural diagram of a wearable device in which the sensing element includes a magnetic sensor. Figures 68 to 69 FIG. 1 is a schematic structural diagram of a wearable device in which the sensing element includes a pressure sensor.

[0462] The sensing element may include an optical sensor 511. Accordingly, the wearable device 100 is provided with a characteristic region that can serve as a marker. For example, the characteristic region may be provided on the input device 120 or the housing 180 of the wearable device 100, as described in detail later. When the input device 120 moves, the optical sensor 511 may detect light reflected by the characteristic region to obtain characteristic information. The processor may then determine the motion information of the input device 120 to determine the user's input.

[0463] When the input device 120 is rotated, the motion information of the input device 120 includes the motion state of the input device 120 being a rotation state and rotation information related to the rotation, wherein the rotation information may include information such as the rotation direction and rotation angle of the input device 120 .

[0464] When the input device 120 is pressed, the input device 120 will move, and the motion information of the input device 120 includes that the motion state of the input device 120 is a moving state and motion information related to the movement, wherein the motion information may include the moving displacement and moving direction of the input device 120, etc. The moving direction may include moving toward the direction close to the shell 180 or moving toward the direction away from the shell 180.

[0465] In the embodiment of the present application, the characteristic region may be a microstructure that is patterned, colored, or marked in other ways. The characteristic region may also be understood as a microstructure comprising multiple points.

[0466] In some embodiments, the characteristic region includes a characteristic texture, which may be a microstructure formed by one or more of scallops, grooves, dimples, protrusions, bumps, scratches, unevenness, and the like.

[0467] In one example, the characteristic texture in the characteristic region changes regularly. For example, the characteristic texture is a hole, and the characteristic region includes a plurality of holes, and the depths of the plurality of holes increase or decrease in sequence.

[0468] In other embodiments, the characteristic region may be a colored microstructure.

[0469] In one example, the color of the feature region changes regularly, for example, the feature region is colored with two colors, and the two colors are distributed alternately.

[0470] As mentioned above, the input device 120 can rotate or move. For the convenience of description, embodiments for identifying the rotation or movement state of the input device 120 are described below.

[0471] First, an embodiment for recognizing the rotation of the input device 120 will be described.

[0472] exist Figures 46 to 49 In a corresponding embodiment, a characteristic region is provided on a region of the head portion 121 that is opposite to the first channel 1231 in the stem portion 122 .

[0473] In some embodiments, reference Figure 46 The main body 101 of the wearable device 100 includes a housing 180, a cover 114, an input device 120, and an optical sensor 511. The cover 114 is connected to the top of the housing 180 to form the surface of the main body 101. In some embodiments, the cover 114 can be a display screen 140. The housing 180 is provided with a mounting hole 181. The input device 120 includes a head 121 and a rod 122. The head 121 extends outward from the housing 180, and the rod 122 is mounted in the mounting hole 181.

[0474] Continue to refer Figure 46 The rod portion 122 is provided with a first channel 1231 that penetrates the rod portion 122 along its axial direction for transmitting light. The optical sensor 511 is provided in the housing 180 on one side of the end portion of the rod portion 122. For example, the optical sensor 511 is provided opposite one end of the first channel 1231 to facilitate transmission of light through the first channel 1231. A characteristic region 1241 is provided in the head portion 121 in an area opposite the other end of the first channel 1231. Light can be transmitted between the characteristic region 1241 and the first channel 1231. Light reflected from the characteristic region 1241 is transmitted to the optical sensor 511 through the first channel 1231. The characteristic information obtained by the optical sensor 511 is used to determine the rotational state of the input device 120 and rotation information related to the rotation, thereby recognizing user input.

[0475] Continue to refer Figure 46 The head 121 includes a first region 1213 communicating with the first channel 1231 , and a characteristic region 1241 is provided on the first region 1213 . In this embodiment, the first region 1213 of the head 121 is the region of the head 121 opposite to the first channel 1231 .

[0476] When the input device 120 is rotated, the light from the light-emitting unit passes through the first channel 1231 of the rod 122 to the characteristic area 1241 of the first area 1213 of the head 121. The characteristic area 1241 reflects the light, and the reflected light passes through the first channel 1231 of the rod 122 again to reach the optical sensor 511 to obtain characteristic information. In this way, the processor connected to the optical sensor 511 can process the characteristic information obtained in multiple time periods to determine the rotation state of the input device 120 and rotation information related to the rotation to identify user input.

[0477] It should be understood that the light-emitting unit can be a light-emitting unit integrated into the optical sensor 511, or a light-emitting unit independent of the optical sensor 511, and the present embodiment does not impose any limitation. For ease of description, the present embodiment takes the light-emitting unit integrated into the optical sensor 511 as an example to illustrate the embodiment.

[0478] In one example, the feature information may be an irregular grayscale image formed on the light sensor 511 by light reflected from the feature region 1241. The processor 110 processes the grayscale image to determine the rotation state of the input device 120 and rotation information related to the rotation, thereby recognizing user input. For example, the processor may determine the rotation state of the input device 120 and rotation information related to the rotation by comparing coordinate points of multiple grayscale images and processing the multiple grayscale images.

[0479] In another example, the characteristic information may be the time at which light is reflected by the characteristic region 1241. The processor 110 analyzes and processes the obtained time to determine whether the input device 120 is in a rotational state and rotation information related to the rotation, thereby recognizing the user input. For example, the processor processes the time difference between multiple obtained times to determine the rotational state of the input device 120 and rotation information related to the rotation.

[0480] In the embodiment of the present application, the characteristic region 1241 can be set at any position of the first region 1213 of the head 121, such as Figure 47 As shown, the characteristic region 1241 is set at the center of the first region 1213. Of course, the characteristic region 1241 can also be set at any position in the first region 1213 except the center, and this embodiment of the application does not impose any limitation.

[0481] In one example, the feature region 1241 includes a feature texture, which may be a microstructure formed by one or more of scallops, grooves, indentations, protrusions, bumps, scratches, unevenness, and the like.

[0482] For example, the characteristic region 1241 includes a characteristic texture.

[0483] For another example, feature region 1241 includes multiple feature textures of the same type, located at different locations within feature region 1241, and exhibiting regular variations. For example, the feature textures may be holes, and the feature region may include multiple holes, with the depths of the holes increasing or decreasing in sequence. Thus, compared to a structure in which a single feature texture is provided within feature region 1241, providing feature region 1241 with multiple feature textures of the same type on head 121 results in the feature textures within feature region 1241 exhibiting regular variations. By analyzing feature information generated from feature region 1241 exhibiting regular variations in feature textures, the computational complexity of processor 110 can be significantly reduced.

[0484] In another example, the feature region 1241 may be a colored microstructure.

[0485] For example, the characteristic region 1241 is colored in one color.

[0486] For another example, the characteristic region 1241 is colored in multiple colors, with the colors changing regularly. For example, the characteristic region 1241 is colored in two colors, with the two colors spaced apart. Thus, compared to a structure where the characteristic region 1241 is colored in a single color, the characteristic region 1241 on the head 121 is colored in multiple colors, with the colors changing regularly. By analyzing the characteristic information generated by the characteristic region 1241 colored in multiple, regularly changing colors, the computational complexity can be greatly reduced.

[0487] In other embodiments, reference Figure 48 The first region 1213 of the head 121 is provided with a hole 1214, and the bottom wall of the hole 1214 is provided with a characteristic region 1241. Furthermore, the hole 1214 can be filled with a transparent material. In this embodiment, the bottom wall of the hole 1214 of the head 121 is the region of the head 121 opposite the first channel 1231.

[0488] When the input device 120 is rotated, light from the light-emitting unit (for example, the light-emitting unit in the optical sensor 511) passes through the first channel 1231 of the rod 122 and through the hole 1214 to reach the characteristic area 1241 on the bottom wall of the hole 1214. It is assumed that the characteristic area 1241 reflects the light, and the reflected light passes through the hole 1214 and the first channel 1231 of the rod 122 again to reach the optical sensor 511 to obtain characteristic information. In this way, the processor 110 connected to the optical sensor 511 can process the characteristic information obtained multiple times to determine the rotation state of the input device 120 and rotation information related to the rotation to identify user input.

[0489] For the detailed description of the characteristic information and the characteristic area 1241 , please refer to the above related description and will not be repeated here.

[0490] In other embodiments, reference Figure 49 ,and Figure 46 The difference is that an optical fiber 520 is disposed within the first channel 1231 of the rod 122. The optical fiber 520 forms a first angle with the axial direction of the rod 122. One end of the optical fiber 520 is disposed opposite the optical sensor 511. When the input device 120 is rotated to a certain angle, the other end of the optical fiber 520 can be disposed opposite the characteristic region 1241. The characteristic region 1241 is spaced a certain distance from the center of the first region 1213. Specifically, the center of the characteristic region 1241 is spaced a certain distance from the center of the first region 1213. In other words, the characteristic region 1241 is located outside the center of the first region 1231.

[0491] In one example, the input device 120 rotates and the optical fiber 520 does not rotate. In this example, the optical fiber 520 may be fixedly connected to the housing 180 and not in contact with the rod 122, so that the optical fiber 520 does not rotate when the input device 120 is rotated. Figure 17 The connector 200 shown implements the placement of an optical fiber 520 on the rod portion 122. For example, the optical fiber 520 can be placed in the cavity of the second connector 220. The end of the second connector 220 away from the head portion 121 can be directly or indirectly fixedly connected to the housing 180. The first connector 210 is sleeved on the second connector 220 and fixedly connected to the rod portion 122 or the head portion 121. In this way, when the input device 120 is rotated, the optical fiber 520 can remain fixed. The phrase "one end of the second connector 220 is indirectly fixedly connected to the housing 180" means that one end of the second connector 220 is fixedly connected to the housing 180 via another component (e.g., a circuit board).

[0492] When the input device 120 is rotated so that the characteristic region 1241 is opposite the other end of the optical fiber 520, light reflected from the characteristic region 1241 can be reflected by the optical fiber 520 onto the optical sensor 511, forming an image on the optical sensor 511 to form characteristic information. When the characteristic region 1241 is misaligned with the other end of the optical fiber 520, the characteristic region 1241 will not be formed on the optical sensor 511. In other words, in this embodiment, the characteristic region 1241 is formed on the optical sensor 511 at intervals through the optical fiber 520. In this way, the pattern and imaging speed of the multiple images of the characteristic region 1241 on the optical sensor 511 can be used to determine the rotational state of the input device 120 and rotation information related to the rotation, thereby recognizing user input.

[0493] For example, the cross-sectional area of ​​the optical fiber 520 can be larger than the area of ​​the characteristic region 1241. When the input device 120 rotates one revolution, the characteristic region 1241 can be aligned with the optical fiber 520 within a certain angle range. In this way, the characteristic region 1241 can be imaged multiple times on the optical sensor 511 through the optical fiber 520. The rotational state of the input device 120 and rotation-related information can be determined based on the patterns and imaging speeds of the multiple images to identify user input, thereby significantly improving computing speed and enhancing the user experience.

[0494] Exemplarily, a plurality of feature areas 1241 may be provided on the first area 1231 of the head 121. Thus, when the input device 120 is rotated one circle, the plurality of feature areas 1241 may be aligned with the optical fiber 520 multiple times, and multiple imaging patterns and imaging speeds may be obtained intermittently on the optical sensor 511, which may better improve the calculation accuracy and thus improve the recognition accuracy.

[0495] It should be understood that the alignment of the characteristic region 1241 with the optical fiber 520 indicates that, in a plane parallel to the rotation direction, the projection of the cross section of the characteristic region 1241 and the projection of the cross section of the optical fiber 520 are at least partially overlapped, and at least partial overlap means that the projections of the two are partially overlapped or completely overlapped.

[0496] It should be understood that in the embodiment where the optical fiber 520 is arranged in the first channel 1231, the characteristic region 1241 may also be arranged as follows: Figure 47 The bottom wall of the hole 1214 shown is not limited in any way in this embodiment of the present application.

[0497] In another example, the optical fiber 520 can rotate with the rotation of the input device 120. In this example, the optical fiber 520 can be fixed in the first channel 1231, and the optical fiber 520 is arranged opposite the characteristic area 1241. Exemplarily, the first channel 1231 of the rod 122 is filled with a filler, and the optical fiber 520 is wrapped by the filler to fix the optical fiber 520 on the rod 122.

[0498] During the rotation of the input device 120, the optical fiber 520 also rotates, and the light reflected from the characteristic area 1241 can be continuously reflected on the optical sensor 511 through the optical fiber 520 to form an image on the optical sensor 511 to form characteristic information. The rotation state of the input device 120 and rotation information related to the rotation are determined based on the characteristic information to identify user input.

[0499] Exemplarily, the characteristic information may be the time when the light is reflected back by the characteristic area 1241. The processor 110 determines the rotation state of the input device 120 and the rotation information related to the rotation by analyzing and processing the time difference between the multiple times obtained to identify the user input.

[0500] For example, the feature information can be the irregular grayscale image formed on the optical sensor 511 by light reflected from the feature region 1241. However, because the optical fiber 520 rotates with the rotation of the input device 120, and the feature region 1241 is imaged on the optical sensor 511 through the optical fiber 520, the imaging trajectory of the feature region 1241 on the optical sensor 511 is annular. In other words, the grayscale image formed by the feature region 1241 on the optical sensor 511 is annular, and the angle of the annular image is the same as the rotation angle of the input device 120. Therefore, the rotation state of the input device 120 and related rotation information can be determined based on the annular imaging trajectory. This significantly reduces computational complexity and improves recognition efficiency.

[0501] exist Figure 50 and Figure 51 In the corresponding embodiment, a characteristic area 1241 is provided on the inner end surface of the head 121 opposite to the shell 180 .

[0502] In some embodiments, reference Figure 50 The head 121 includes an inner end surface 121-C close to the shell 180 and opposite to the shell 180, and a characteristic area 1241 is provided on the inner end surface 121-C. Correspondingly, a portion of the shell 180 close to the inner end surface 121-C is provided with a third channel 182 for transmitting light. When the input device 120 is rotated to a certain angle, one end of the third channel 182 can be arranged opposite to the characteristic area 1241, and an optical sensor 511 is provided on one side of the other end of the third channel 182. Exemplarily, the optical sensor 511 is arranged opposite to one end of the third channel 182 to better transmit light through the third channel 1182. Light can be transmitted between the optical sensor 511, the third channel 182 and the characteristic area 1241. Among them, the relevant description of the characteristic area 1241 can refer to the above description and will not be repeated.

[0503] In this embodiment, the characteristic area 1241 is based on the imaging principle of the optical sensor 511 and Figure 49 The imaging principle of the characteristic area 1241 shown on the optical sensor 511 through the optical fiber 520 that does not rotate with the rotation of the input device 120 is similar. When the input device 120 is rotated, the characteristic area 1241 is intermittently aligned with the third channel 182, and the characteristic area 1241 is intermittently imaged on the optical sensor 511.

[0504] Specifically, when the input device 120 is rotated so that the characteristic region 1241 is aligned with the third channel 182, light reflected from the characteristic region 1241 can be reflected by the third channel 182 onto the optical sensor 511, thereby forming an image on the optical sensor 511 to form characteristic information. When the characteristic region 1241 is misaligned with the third channel 182, the characteristic region 1241 will not be formed on the optical sensor 511. In other words, in this embodiment, the characteristic region 1241 is formed on the optical sensor 511 at intervals through the third channel 182. In this way, the pattern and imaging speed of multiple images of the characteristic region 1241 on the optical sensor 511 can be used to determine motion information of the input device 120 and identify user input.

[0505] It should be understood that the alignment of the characteristic region 1241 with the third channel 182 indicates that, in a plane parallel to the direction of rotation, the projection of the cross section of the characteristic region 1241 and the projection of the cross section of the third channel 182 are at least partially overlapped, and at least partial overlap means that the projections of the two are partially overlapped or completely overlapped.

[0506] It should be noted that a hole may also be provided on the inner end surface 121 -C, and a characteristic area 1241 may be provided on the bottom wall of the hole, and this embodiment of the present application does not impose any limitation thereto.

[0507] In this embodiment, a characteristic region 1241 is provided on the inner end surface 121 -C of the head 121 , and a third channel 182 opposite to the characteristic region 1241 is provided on the shell 180 . The structure is relatively simple and the cost is low.

[0508] In other embodiments, reference Figure 51 A characteristic region 1241 is provided on the inner end surface 121-C of the head portion 121. A first channel 1231 for transmitting light is provided within the shaft portion 122. A first opening 1221 and a first polarizer 531 are provided at the end of the shaft portion 122 near the head portion 121. The first opening 1221 is disposed opposite the characteristic region 1241 to transmit light to the characteristic region 1241 through the first channel 1231, the first polarizer 531, and the first opening 1221. Simultaneously, light reflected from the characteristic region 1241 is transmitted to the optical sensor 511 through the first opening 1221, the first polarizer 531, and the first channel 1231, thereby generating characteristic information to determine the rotational state of the input device 120 and rotation information related thereto, thereby identifying user input. The description of the characteristic region 1241 can be found above and will not be repeated here.

[0509] Continue to refer Figure 51, the first opening 1221 is provided in the rod portion 122, and the first opening 1221 extends inward from the side wall of the rod portion 122 and is connected to the first channel 1231, so that light can be transmitted between the first channel 1231, the first opening 1221 and the characteristic area 1241. Exemplarily, the extension direction of the first opening 1221 is perpendicular to the axial direction of the rod portion 122. In order to prevent external impurities such as dust or water from entering the interior of the wearable device 100 through the first opening 1221, in one example, a transparent material can be filled in the first opening 1221 to form the first opening 1221 having the transparent material. In another example, a transparent cover can be installed on the first opening 1221.

[0510] Continue to refer Figure 51 The first polarizer 531 is adjacent to and opposite to the first opening 1221, so that light can pass from the first opening 1221 to the first polarizer 531, or light can pass from the first polarizer 531 to the first opening 1221. For example, a portion of the first polarizer 531 can extend into the first opening 1221. For example, the first channel 1231 is filled with a transparent material, and the first polarizer 531 is wrapped in the transparent material to secure the first polarizer 531 to the rod 122.

[0511] In this embodiment, the purpose of the first polarizer 531 is to change the optical path so that as much light as possible is transmitted between the optical sensor 511 and the feature area 1241. Moreover, in the embodiment of the present application, the first polarizer 531 is mainly used to change the optical path of the incident light as parallel light, and the incident light at other angles can be ignored. Therefore, when setting the first polarizer 531, the position design of the first polarizer 531 when the incident light is parallel light is mainly considered. Taking the axial direction of the rod 122 as the reference point, the first polarizer 531 forms a first angle with the axial direction of the rod 122. The polarization angle of the first polarizer 531 and the first angle meet the following conditions: the polarization angle of the first polarizer 531 and the first angle are complementary, that is, the sum of the polarization angle of the first polarizer 531 and the first angle is 90°. For ease of description, the first angle is denoted as β1. In one example, the first angle β1 is 45°. It is understandable that the first angle β1 between the first polarizer 531 and the rod portion 122 in the axial direction may also be other angles, for example, β1 = 40°, as long as the first polarizer 531 can transmit light between the optical sensor 5110 and the characteristic area 1241 .

[0512] In the embodiment of the present application, the polarization angle of the first polarizer 531 represents the angle between the incident light and the normal line. The polarization angles of other polarizers below are explained in the same way and will not be repeated here.

[0513] When the input device 120 is rotated, light from the light emitting unit (for example, the light emitting unit in the optical sensor 511) passes through the first channel 1231 of the rod 122 and reaches the first polarizer 531. The light reflected or refracted from the first polarizer 531 ( Figure 51 The reflected light (shown is the reflected light) passes through the first opening 1221 to reach the characteristic area 1241, and the characteristic area 1241 reflects the light. The reflected light passes through the first opening 1221, the first polarizer 531 and the first channel 1231 again to reach the optical sensor 511 to obtain characteristic information. In this way, the processor connected to the optical sensor 511 can process the characteristic information to determine the rotation state of the input device 120 and rotation information related to the rotation to identify user input.

[0514] It should be understood that the characteristic area 1241 and the first channel 1231 are both provided on the input device 120. When the input device 120 is rotated, the characteristic area 1241 continuously reflects light to form an image on the optical sensor 511 to generate characteristic information. The principle of determining the motion information of the input device 120 based on the characteristic information is similar to that of the first channel 1231. Figure 46 and Figure 48 The corresponding embodiments are the same, and for detailed descriptions, please refer to the relevant descriptions above and will not be repeated here.

[0515] In this embodiment, a characteristic area 1241 is provided on the inner end surface 121-C of the head 121, and a first channel 1231, a first polarizer 531 and a first opening 1221 are provided on the rod 122. The first polarizer 531 can not only change the light path, transmit the light from the light-emitting unit (for example, the light-emitting unit in the optical sensor 511) to the characteristic area 1241 and transmit the light reflected from the characteristic area 1241 to the optical sensor 511, but also the first polarizer 531 can effectively filter out external ambient light, so that ambient light at some angles cannot pass through the first opening 1221 and the first channel 1231 to reach the optical sensor 511, thereby greatly reducing the interference of ambient light on the recognition of motion information of the input device 120 and improving the user experience.

[0516] It should be understood that when the characteristic area 1241 is set on the inner end surface 121-C of the head 121, the polarizer 531 does not need to be set in the input device 120. A small amount of light will reach the characteristic area 1241 and be reflected from the characteristic area 1241 to the light sensor 511. However, the imaging effect of the light reflected back from the characteristic area 1241 on the light sensor 511 is poor.

[0517] exist Figure 52 and Figure 53In a corresponding embodiment, a characteristic area 1241 is provided on an area of ​​the housing 18 that is opposite to the rod portion 122 or the head portion 121 of the input device 120 .

[0518] In some embodiments, reference Figure 52 A characteristic area 1241 is provided on the side 180-A of the shell 180, and the optical sensor 511 is arranged opposite to the end of the rod 122. In order to be able to transmit light between the optical sensor 511 and the characteristic area 1241 to determine the motion information of the input device 120 through the characteristic information of the characteristic area 510, channels can be provided on both the rod 122 and the head 121, and at the same time, a polarizer is used to change the light path.

[0519] Continue to refer Figure 52 A first channel 1231 is provided on the rod 122, and a fourth channel 1233 is provided on the head 121. The extension direction of the fourth channel 1233 is perpendicular to the axial direction of the rod 122, that is, the extension direction of the fourth channel 1233 is perpendicular to the extension direction of the first channel 1231. One end of the first channel 1231 is arranged opposite to the optical sensor 511, and the other end of the first channel 1231 is connected to one end of the fourth channel 1233. When the input device 120 is rotated to a preset angle, the other end of the fourth channel 1233 can be arranged opposite to the feature area 1241.

[0520] For example, polarizers are provided at both ends of the fourth channel 1233, which are denoted as a second polarizer 532 and a third polarizer 533. The second polarizer 532 is provided at one end of the fourth channel 1233 connected to the first channel 1231, and the third polarizer 533 is provided at the other end of the fourth channel 1233. The second polarizer 532 is used to reflect or refract ( Figure 52 As shown, the light is reflected) so that the light can be transmitted as straight as possible in the fourth channel 1233, and the second polarizer 532 is also used to reflect the light reflected by the feature area 1241 and the light reflected or refracted by the third polarizer 533 ( Figure 52 The third polarizer 533 is used to reflect the light reflected or refracted by the second polarizer 532 ( Figure 52 The light (shown is the reflected light) continues to reflect or refract so that the light can reach the characteristic area 1241. The third polarizer 533 is also used to continue to reflect or refract the light reflected by the characteristic area 1241 so that the light can be transmitted as straightly as possible in the fourth channel 1233 to reach the second polarizer 532, and the light is transmitted to the light sensor 511 through the second polarizer 532 and the first channel 1231.

[0521] Illustratively, the fourth channel 1233 is filled with a transparent material, and the second polarizer 532 and the third polarizer 533 are wrapped by the transparent material to fix the second polarizer 532 and the third polarizer 533 on the head 121 .

[0522] In this embodiment, two polarizers are connected with Figure 51 The first polarizer 531 provided in the corresponding embodiments has the same purpose: to change the optical path so that as much light as possible is transmitted between the optical sensor 511 and the characteristic region 1241. Furthermore, the two polarizers are primarily used to change the incident light when it is parallel, and incident light at other angles can be ignored. Therefore, when providing the two polarizers, the primary consideration is the design of the polarizer positions when the incident light is parallel.

[0523] Taking the axial direction of the rod 122 as a reference point, the second polarizer 532 forms a second angle with the axial direction of the rod 122, and the third polarizer 533 forms a third angle with the axial direction of the rod 122. The second angle and the polarization angle of the second polarizer 532 satisfy the following conditions: the second angle and the polarization angle of the second polarizer 532 are complementary, that is, the sum of the polarization angle of the second polarizer 532 and the second angle is 90°; and the third angle and the polarization angle of the third polarizer 533 satisfy the following conditions: the third angle and the polarization angle of the third polarizer 533 are complementary, that is, the sum of the polarization angle of the third polarizer 533 and the third angle is 90°.

[0524] For ease of description, the second angle β2 is recorded as β2, and the third angle β3 is recorded as β3. In one example, the second angle β2 is 45°. In another example, the third angle β3 is 45°.

[0525] It should be understood that the second angle β2 between the second polarizer 532 and the rod portion 122 in the axial direction may also be other angles. Similarly, the third angle β3 between the third polarizer 533 and the rod portion 122 in the axial direction may also be other angles. The embodiments of the present application do not impose any limitations, as long as the combination of the second polarizer 532 and the third polarizer 533 can enable light to be transmitted between the optical sensor 511 and the characteristic area 1241.

[0526] In this embodiment, since the housing 180 is stationary, when the input device 120 is rotated, the characteristic area 1241 is intermittently aligned with the fourth channel 1233 and is intermittently imaged on the optical sensor 511. Therefore, the imaging principle of the characteristic area 1241 on the optical sensor 511 is the same as that of the embodiment. Figure 49 The principle of imaging the characteristic region 1241 shown on the optical sensor 511 by the optical fiber 520 that does not rotate with the rotation of the input device 120 is similar.

[0527] Specifically, the light from the light-emitting unit (for example, the light-emitting unit in the optical sensor 511) passes through the first channel 1231 of the rod 122 to reach the fourth channel 1233, and the light reflected or refracted from the second polarizer 532 reaches the third polarizer 533. When the input device 120 rotates to align the characteristic area 1241 with the fourth channel 1233, the light reflected or refracted by the third polarizer 533 reaches the characteristic area 1241, and the light reflected by the characteristic area 1241 reaches the fourth channel 1233 again. The light reflected or refracted by the third polarizer 533 and the second polarizer 532 passes through the first channel 1231 to reach the optical sensor 511, and is imaged on the optical sensor 511 to form characteristic information. When the characteristic area 1241 is misaligned with the fourth channel 1233, the characteristic area 1241 will not be imaged on the optical sensor 511. That is, in this embodiment, the characteristic area 1241 is intermittently imaged on the optical sensor 511 through the fourth channel 1233. In this way, the pattern of multiple imaging of the characteristic area 1241 on the optical sensor 511 and the imaging speed can be used to determine the motion information of the input device 120 to identify user input.

[0528] It should be understood that the alignment of the characteristic region 1241 with the fourth channel 1233 indicates that, in a plane parallel to the rotation direction, the projection of the cross section of the characteristic region 1241 and the projection of the cross section of the fourth channel 1233 are at least partially overlapped, and at least partial overlap means that the projections of the two are partially overlapped or completely overlapped.

[0529] It should also be understood that when the characteristic area 1241 is set on the side 180-A of the shell 180, the polarizer 531 does not need to be set in the input device 120. A small amount of light will reach the characteristic area 1241 and be reflected from the characteristic area 1241 to the light sensor 511. However, the imaging effect of the light reflected back from the characteristic area 1241 on the light sensor 511 is poor.

[0530] In other embodiments, reference Figure 53A mounting hole 181 is provided on the shell 180, and the rod 122 of the input device 120 is provided in the mounting hole 181. A characteristic area 1241 is provided on the hole wall 1811 of the mounting hole 181, and a second opening 1222 opposite to the characteristic area 1241 and a first channel 1231 connected to the second opening 1222 are provided on the rod 122. A fourth polarizer 534 is provided in the first channel 1231, and the optical sensor 511 is arranged opposite to the first channel 1231. Light is transmitted between the optical sensor 511 and the characteristic area 1241 through the first channel 1231, the fourth polarizer 534 and the second opening 1222, so that the light reflected by the characteristic area 1241 is transmitted to the optical sensor 511 through the second opening 1222, the fourth polarizer 534 and the first channel 1231, thereby generating characteristic information to determine the motion information of the input device 120 and identify the user input.

[0531] Continue to refer Figure 53 The second opening 1222 is provided on the rod portion 122. The second opening 1222 extends inward from the side wall of the rod portion 122 and is in communication with the first channel 1231, so that light can be transmitted between the second opening 1222 and the characteristic area 1241. Exemplarily, the extension direction of the second opening 1222 is perpendicular to the axial direction of the rod portion 122. In order to prevent external impurities such as dust or water from entering the interior of the wearable device 100 through the second opening 1222, in one example, the second opening 1222 can be filled with a transparent material to form a second opening 1222 having a transparent material. In another example, a transparent cover can be installed on the second opening 1222.

[0532] Continue to refer Figure 53 The fourth polarizer 534 is adjacent to and opposite to the second opening 1222, so that light can pass from the second opening 1222 to the fourth polarizer 534, or light can pass from the fourth polarizer 534 to the second opening 1222. Exemplarily, the first channel 1231 is filled with a transparent material, and the fourth polarizer 534 is wrapped by the transparent material to secure the fourth polarizer 534 to the first channel 1231.

[0533] In this embodiment, the fourth polarizer 534 and Figure 51 The first polarizer 531 provided in the corresponding embodiments has the same purpose: to change the optical path so that as much light as possible is transmitted between the optical sensor 511 and the characteristic region 1241. Furthermore, the fourth polarizer 534 is primarily used to change the incident light when it is parallel, while ignoring incident light at other angles. Therefore, when setting the fourth polarizer 534, the primary consideration is the design of the polarizer's position when the incident light is parallel.

[0534] Taking the axial direction of the rod 122 as a reference point, the fourth polarizer 534 forms a fourth angle with the axial direction of the rod 122, and the polarization angle of the fourth polarizer 534 and the fourth angle satisfy the following condition: the polarization angle of the fourth polarizer 534 and the fourth angle are complementary to each other, that is, the sum of the polarization angle of the fourth polarizer 534 and the fourth angle is 90°.

[0535] For the convenience of description, the fourth angle is recorded as β4. In one example, the fourth angle β4 is 45°.

[0536] It should be understood that the fourth angle β4 between the fourth polarizer 534 and the rod portion 122 in the axial direction can also be other angles, and the embodiments of the present application do not impose any limitations thereon, as long as the fourth polarizer 534 can transmit light between the optical sensor 511 and the characteristic area 1241.

[0537] In this embodiment, since the housing 180 is stationary, when the input device 120 is rotated, the characteristic area 1241 is intermittently aligned with the second opening 1222 and is intermittently imaged on the optical sensor 511. Therefore, the imaging principle of the characteristic area 1241 on the optical sensor 511 is the same as that of the embodiment. Figure 49 The principle of imaging the characteristic region 1241 shown on the optical sensor 511 by the optical fiber 520 that does not rotate with the rotation of the input device 120 is similar.

[0538] Specifically, the light from the light emitting unit (for example, the light emitting unit in the optical sensor 511) passes through the first channel 1231 of the rod 122 and reaches the fourth polarizer 534. When the input device 120 rotates to the point where the characteristic area 1241 is opposite to the second opening 1222, the light reflected or refracted from the fourth polarizer 534 ( Figure 53 The light after reflection is shown) passes through the second opening 1222 to reach the characteristic area 1241, and the light reflected from the characteristic area 1241 reaches the second opening 1222 again, and the light after reflection or refraction by the fourth polarizer 534 ( Figure 53 The light (shown as reflected light) passes through the first channel 1231 and reaches the optical sensor 511, where it forms an image on the optical sensor 511 to form characteristic information. When the characteristic region 1241 is misaligned with the second opening 1222, the characteristic region 1241 will not form an image on the optical sensor 511. In other words, in this embodiment, the characteristic region 1241 forms an image on the optical sensor 511 at intervals. In this way, the pattern and imaging speed of the multiple images of the characteristic region 1241 on the optical sensor 511 can be used to determine the motion information of the input device 120 to identify user input.

[0539] It should be understood that the alignment of the characteristic area 1241 with the second opening 1222 means that, in a plane perpendicular to the rotation direction, the projection of the cross section of the characteristic area 1241 and the projection of the cross section of the second opening 1222 are at least partially overlapped, and at least partial overlap means that the projections of the two are partially overlapped or completely overlapped.

[0540] exist Figures 54 to 57 In the corresponding embodiment, a characteristic area 1241 is provided on the inner end surface 122 -A of the rod portion 122 .

[0541] In some embodiments, reference Figure 54 and Figure 55 A characteristic area 1241 is provided on the inner end surface 122 -A of the rod portion 122 away from the head portion 121 , and the optical sensor 511 is arranged opposite to the inner end surface 122 -A of the rod portion 122 .

[0542] Continue to refer Figure 54 and Figure 55 For example, a first channel 1231 may be provided in the rod portion 122. For example, in the embodiment described above where the fingerprint sensor 130C is provided in the head portion 121, the rod portion 122 may be provided with the first channel 1231 to transmit light between the fingerprint sensor 130C and the light sensor 511. Therefore, in the embodiment where the first channel 1231 is provided in the rod portion 122 along the axial direction of the rod portion 122 and passes through the rod portion 122, the characteristic region 1241 may be provided on the inner end surface 122-A and outside the first channel 1231.

[0543] In one example, characteristic region 1241 may include one or more characteristic textures. When characteristic region 1241 includes multiple characteristic textures, the multiple characteristic textures are of the same type, are located at different locations outside first channel 1231 of inner end surface 122-A, and exhibit a regular pattern of changes. For example, the characteristic texture is a hole, and the characteristic region includes multiple holes, with the depths of the multiple holes increasing or decreasing in sequence.

[0544] In another example, the characteristic region 1241 may be a colored microstructure. The characteristic region 1241 may be colored in one or more colors. When the characteristic region 1241 is colored in multiple colors, the multiple colors change regularly. For example, the characteristic region may be colored in two colors, and the two colors may be distributed alternately.

[0545] For a detailed description of the feature area 1241, please refer to Figure 46 and Figure 47 The description of the feature area 1241 is omitted here.

[0546] It should be understood that in an embodiment where the first channel 1231 is not provided in the rod portion 121 , the characteristic region 1241 can be provided at any position on the inner end surface 122 -A of the rod portion 122 , and this embodiment of the present application does not impose any limitation thereto.

[0547] When the input device 120 is rotated, light from the light-emitting unit (for example, the light-emitting unit in the optical sensor 511) reaches the characteristic area 1241 on the inner end surface 122-A of the rod 122. The characteristic area 1241 reflects the light, and the reflected light reaches the optical sensor 511 to obtain characteristic information. In this way, the processor connected to the optical sensor 511 can process the characteristic information obtained in multiple time periods to determine the motion information of the input device 120 to identify user input.

[0548] In other embodiments, reference Figure 56 and Figure 57 A grating-like structure 1242 may be provided on the inner end surface 122 -A of the rod portion 122 , and the optical sensor 511 is arranged opposite to the inner end surface 122 -A of the rod portion 122 to transmit light between the optical sensor 511 and the grating-like structure 1242 .

[0549] Grating-like structure 1242 is a photoelectric detection element created by designing known features that can serve as markers and utilizing these known features to detect phenomena such as projection, diffraction, refraction, and reflection of light. In this embodiment of the present application, the grating-like structure can be used to detect the rotational state of input device 120 and rotation information related to the rotation to identify user input. It should be understood that grating-like structure 1242 in this embodiment of the present application can be understood as an example of the feature region 1241 having multiple characteristic textures described above.

[0550] For example, continue to refer to Figure 56 and Figure 57 The grating-like structure 1242 may be an element provided with a plurality of holes 1242 - 1 , that is, in this example, the characteristic texture is a hole.

[0551] In one example, the grating-like structure 1242 includes a plurality of holes 1242-1, and the depths of the plurality of holes 1242-1 are different. For example, the depths of the plurality of holes 1242-1 increase or decrease sequentially. Figure 57 In (b), the depths of the holes 1242 - 1 at both ends of the grating-like structure 1242 are different, and the depth of the hole 1242 - 1 at the top end of the grating-like structure 1242 is smaller than the depth of the hole 1242 - 1 at the bottom end of the grating-like structure 1242 .

[0552] In another example, the grating-like structure 1242 includes a plurality of holes 1242 - 1 , and the hole wall of each hole 1242 - 1 is plated with a color. The colors of the hole walls of the plurality of holes 1242 - 1 may be different.

[0553] In one example, continue to refer to Figure 56 and Figure 57 The grating-like structure 1242 can be a separate component fixedly connected to the inner end surface 122-A of the rod portion 122, thereby forming a grating-like structure 1242 disposed on the inner end surface 122-A. In an embodiment in which the first channel 1231 is disposed within the rod portion 122, the grating-like structure 1242 is annular in shape, and the hollow region 1242-2 of the grating-like structure is used to avoid the first channel 1231. For example, the grating-like structure 1242 can be bonded to the inner end surface 122-A of the rod portion 122.

[0554] In another example, the inner end surface 122 -A of the rod portion 122 can be directly designed as a grating-like structure 1242 (not shown in the figure), forming an inner end surface 122 -A having a grating-like structure 1242 .

[0555] It should be understood that the grating-like structure 1242 may include not only multiple holes, but also multiple grooves, multiple scratches, and other characteristic textures with concave areas, and the depths of the multiple characteristic textures with concave areas may be different.

[0556] It should also be understood that the grating-like structure 1242 may also include a plurality of protrusions or other characteristic textures with heights, and the heights of the plurality of characteristic textures with heights may be different.

[0557] In this embodiment, during the rotation of the input device 120, the grating-like structure 1242 will form multiple patterns with characteristic regularity on the light sensor 511. The processor 110 connected to the light sensor 511 can determine the rotation state of the input device 120 and rotation information related to the rotation based on the differences between the multiple patterns or the time difference between the multiple patterns reflected to the light sensor 511 to identify user input.

[0558] exist Figures 46 to 57 In the corresponding embodiment, the optical sensor 511 is arranged relative to the rod 122. It can be understood that the relative position relationship between the optical sensor 511 and the rod 122 is only for schematic illustration. In fact, the optical sensor 511 can be placed in any other possible position. However, in other positions, corresponding polarizers may need to be set to change the direction of the incident light reaching the rod 122 to achieve Figures 46 to 57 The specific design of the corresponding embodiment of determining the motion information of the input device 120 may be determined according to actual conditions.

[0559] In some embodiments, reference Figure 58 The optical sensor 511 is provided on one side of the side surface in the circumferential direction of the rod portion 122, and a polarizer is provided on one side of the end of the rod portion 122 away from the head portion 121, which is denoted as the fifth polarizer 535. Assume that a light-emitting unit is integrated into the optical sensor 511, the angle between the emitted light from the light-emitting unit and the direction parallel to the axial direction of the rod portion 122 (denoted as the horizontal direction) is γ, the angle between the fifth polarizer 535 and the horizontal direction is β, the polarization angle of the fifth polarizer 535 is α, and the relationship among γ, β, and α is as follows: β = 180° - γ, α + β = 90°. In this way, the direction of the incident light can be changed to parallel light incident on the rod portion 122 along the horizontal direction.

[0560] Above, combined Figures 46 to 58 , an embodiment for identifying the rotation of the input device 120 is described below, and an embodiment for identifying the pressing of the input device 120 is described below.

[0561] Continue to refer Figure 53 ,exist Figure 53 In the structure shown, light is transmitted between the optical sensor 511 and the characteristic area 1241 through the first channel 1231, the fourth polarizer 534 and the second opening 1222, so that the light reflected by the characteristic area 1241 is transmitted to the optical sensor 511 through the second opening 1222, the fourth polarizer 534 and the first channel 1231, generating characteristic information to determine the motion information of the input device 120 and identify the user input.

[0562] When the input device 120 is pressed, the input device 120 moves along the axial direction of the rod 122. The motion information of the input device 120 may include that the motion state of the input device 120 is a moving state and movement information related to the movement. For example, the movement information may include the movement displacement and movement direction of the input device 120.

[0563] When the input device 120 is pressed so that the input device 120 moves along the axial direction, the second opening 1222 on the rod 122 is intermittently aligned with the characteristic area 1241. When the second opening 1222 is aligned with the characteristic area 1241, the light reflected by the characteristic area 1241 will reach the optical sensor 511. When the second opening 1222 of the rod is staggered with the characteristic area 1241, the light will not reach the characteristic area 1241.

[0564] Specifically, when the input device 120 is pressed, light from the light-emitting unit (for example, the light-emitting unit in the optical sensor 511) passes through the first channel 1231 of the rod 122 to reach the fourth polarizer 534. When the input device 120 moves to the characteristic area 1241 and aligns with the second opening 1222, the light reflected from the fourth polarizer 534 passes through the second opening 1222 to reach the characteristic area 1241. The light reflected from the characteristic area 1241 reaches the second opening 1222 again. The light reflected by the fourth polarizer 534 passes through the first channel 1231 and is reflected on the optical sensor 511 to form an image on the optical sensor 511 to form characteristic information. When the characteristic area 1241 is misaligned with the second opening 1222, the characteristic area 1241 will not be imaged on the optical sensor 511. That is, in this embodiment, the characteristic area 1241 is imaged on the optical sensor 511 at intervals. In this way, the pattern of multiple images of the characteristic area 1241 on the optical sensor 511 or the time difference of the light reflected from the characteristic area 1241 to the optical sensor 511 can be used to determine the movement state of the input device 120 and the movement information related to the movement to identify the user input.

[0565] It should be noted that although images are formed on the optical sensor 511 when the input device 120 is rotated or pressed, the pattern formed on the optical sensor 511 when the input device 120 is rotated is different from the pattern formed when the input device 120 is pressed. Therefore, the rotation and pressing of the input device 120 can be distinguished based on the patterns. In some embodiments, to simultaneously identify the rotation and pressing of the input device 120, two holes can be provided in the first channel 1231: one hole for identifying the rotation of the input device 120, and the other hole for identifying the pressing of the input device 120.

[0566] Continue to refer Figure 56 and Figure 57 A grating-like structure 1242 is provided on the inner end surface 122-A of the rod portion 122. The grating-like structure 1242 includes a plurality of holes 1242-1 having different depths. When the input device 120 is pressed to cause the input device 120 to move in the axial direction, light from a light-emitting unit (e.g., a light-emitting unit within the optical sensor 511) reaches the grating-like structure 1242 on the inner end surface 122-A of the rod portion 122. The light reflected by the grating-like structure 1242 reaches the optical sensor 511, generating feature information. The feature information is used to determine the movement state of the input device 120 and movement information related to the movement, thereby identifying user input. For example, the feature information may be the time difference between the time when light is reflected from each hole to the optical sensor 511 and the time when light is reflected from the planar area of ​​the inner end surface 122-A other than the grating-like structure 1242 to the optical sensor 511.

[0567] refer to Figure 59 The sensing element may include a capacitive sensor 512, which is disposed opposite to the end of the rod 122 away from the head 121. A first metal electrode is disposed in the capacitive sensor 512. In order to more easily detect the change in capacitance, the first metal electrode is disposed in the area other than the center of the capacitive sensor 512. Figure 60 A first channel 1231 is provided in the rod portion 122 of the input device 120. The first channel 1231 is a cavity structure. The opening of the first channel 1231 faces the capacitive sensor 512. The first channel 1231 extends from the inner end surface 122-A of the rod portion 122 to the interior of the rod portion 122. A second metal electrode 1243 is provided on the inner wall 1231-A of the first channel 1231 along the circumferential direction of the inner wall 1231-A of the first channel 1231.

[0568] It should be understood that the capacitance sensor 512 here can be Figure 1 The capacitive sensor 130D shown is interchangeable.

[0569] The second metal electrode 1243 may have a differentiated structure in the circumferential direction, so that when the input device 120 is rotated or moved, a changing capacitance between the second metal electrode 1243 and the first metal electrode may be detected.

[0570] In one example, the second metal electrode 1243 is annular in shape and is disposed on the inner wall 1231 -A of the first channel 1231 .

[0571] For example, the angle of the ring structure of the second metal electrode 1243 is less than 360 degrees, so that the changing capacitance between the second metal electrode 1243 and the first metal electrode can be detected when the input device 120 is rotated or moved.

[0572] In another example, the size of the second metal electrode 1243 in the circumferential direction is not uniform, but may vary regularly.

[0573] It should be noted that although Figure 59 The first channel 1231 of the rod portion 122 shown in the figure penetrates the rod portion 122 along the axial direction of the rod portion 122, that is, the first channel 1231 extends from the inner end surface 122-A of the rod portion 122 to the end of the rod portion 122 close to the head 121. However, it should be understood that the first channel 1231 of the rod portion 122 can extend from the inner end surface 122-A to any position of the rod portion 122, and the embodiment of the present application does not impose any limitation thereto. Figure 59The structure shown is for schematic illustration only. Similarly, the second metal electrode 1243 may also extend to any position of the inner wall 1231-A of the first channel 1231, and this embodiment of the present application does not impose any limitation thereto. Figure 59 The structures shown are for illustrative purposes only.

[0574] In this embodiment, the second metal electrode 1243 interacts with the first metal electrode in the capacitive sensor 512 to generate capacitance. When the input device 120 moves, the capacitance between the second metal electrode 1243 and the first metal electrode changes. The capacitive sensor 512 or a processor connected to the capacitive sensor 512 can determine the movement information of the input device 120 by processing and analyzing the changed capacitance to identify user input.

[0575] When the input device 120 is rotated, the second metal electrode 1243 also rotates. Since the second metal electrode 1243 is set in a partial area of ​​the inner wall 1231-A of the first channel 1231, during the rotation process, the second metal electrode 1243 will move closer to or away from the first metal electrode. Therefore, the capacitance between the second metal electrode 1243 and the first metal electrode will change. The capacitance sensor 512 or the processor connected to the capacitance sensor 512 determines the rotation state of the input device 120 and rotation information related to the rotation by analyzing the changed capacitance.

[0576] In one example, when the second metal electrode 1243 is close to the first metal electrode, the capacitance increases, and when the second metal electrode 1243 is far away from the first metal electrode, the capacitance decreases.

[0577] In another example, the rotation state of the input device 120 can be determined based on the change curve of the capacitance. For example, assuming that the capacitance generated by the second metal electrode 1243 and the first metal electrode is the largest when the input device 120 is in the initial position (e.g., Figure 59 As shown in the state shown in FIG, then, during the rotation of the input device 120, the capacitance gradually decreases, or the capacitance gradually decreases and then increases.

[0578] In another example, there is a correspondence between the capacitance variation range and the rotation angle, where one capacitance variation range corresponds to one rotation angle, and the rotation angle can be determined based on the capacitance variation range. For example, three correspondences between capacitance variation ranges and rotation angles are preset: capacitance variation range #1 corresponds to rotation angle #1, capacitance variation range #2 corresponds to rotation angle #2, and capacitance variation range #3 corresponds to rotation angle #3. In this way, the rotation angle can be determined based on the detected capacitance variation range.

[0579] When the input device 120 is pressed, the input device 120 moves along the axial direction of the rod 122, and the distance between the second metal electrode 1243 and the first metal electrode changes, causing the capacitance between the second metal electrode 1243 and the first metal electrode to change. The capacitance sensor 512 or the processor connected to the capacitance sensor 512 determines the movement state of the input device 120 and movement information related to the movement by analyzing the changed capacitance.

[0580] In one example, when the input device 120 moves toward a direction closer to the capacitive sensor 512, the distance between the second metal electrode 1243 and the first metal electrode decreases and the capacitance increases. When the input device 120 moves toward a direction away from the capacitive sensor 512, the distance between the second metal electrode 1243 and the first metal electrode increases and the capacitance decreases.

[0581] In another example, the movement state of the input device 120 can be determined based on the capacitance change curve. For example, assuming that the capacitance generated by the second metal electrode 1243 and the first metal electrode is the largest when the input device 120 is in the initial position, then the capacitance gradually increases as the input device 120 is pressed.

[0582] In another example, there is a correspondence between the capacitance variation range and the displacement, where one capacitance variation range corresponds to one displacement, and the displacement can be determined based on the capacitance variation range. For example, three correspondences between capacitance variation ranges and displacements are preset: capacitance variation range #1 corresponds to displacement #1, capacitance variation range #2 corresponds to displacement #2, and capacitance variation range #3 corresponds to displacement #3. In this way, the displacement can be determined based on the detected capacitance variation range.

[0583] For example, a plurality of second metal electrodes 1243 may be provided on the inner wall 1231-A of the first channel 1231 of the rod portion 122. The plurality of second metal electrodes 1243 are asymmetrically arranged, and the motion information of the input device 120 is determined by the change in capacitance between the plurality of second metal electrodes 1243 and the first metal electrode to identify user input. Figure 61 As shown, two second metal electrodes 1243 are provided on the inner wall 1231 -A of the first channel 1231 of the rod portion 122 , and the two metal electrodes 1243 are asymmetrically arranged.

[0584] In other embodiments, reference Figure 62 and Figure 63, a second metal electrode 1243 may also be provided on the inner end surface 122-A of the rod portion 1122 of the input device 120. The second metal electrode 1243 is provided on the inner end surface 122-A in a fan-shaped structure, and the capacitive sensor 512 is provided opposite to the second metal electrode 1243. Similarly, the interaction between the second metal electrode 1243 and the first metal electrode in the capacitive sensor 512 will generate capacitance. When the input device 120 moves, the capacitance between the second metal electrode 1243 and the first metal electrode changes. The capacitive sensor 512 or the processor connected to the capacitive sensor 512 can determine the motion information of the input device 120 by processing and analyzing the changed capacitance to identify the user input. Among them, when the input device 120 is rotated or pressed, the specific description of determining the motion information of the input device 120 based on the change in capacitance to identify the user input can refer to the above description Figure 59 and Figure 60 The description is not repeated here.

[0585] Exemplarily, the inner end surface 122-A of the rod portion 122 can be provided with a plurality of second metal electrodes 1243 (not shown in the figure), and the plurality of second metal electrodes 1243 are asymmetrically arranged. The movement information of the input device 120 is determined by the change in capacitance between the plurality of second metal electrodes 1243 and the first metal electrode to identify user input.

[0586] refer to Figure 64 The sensing element may include a magnetic sensor 513, a coil is provided in the magnetic sensor 513, and the magnetic sensor 513 is provided opposite to the end of the rod 122 away from the head 121. Figure 65 A first channel 1231 is provided in the rod portion 122 of the input device 120, and the opening of the first channel 1231 faces the magnetic sensor 513. The first channel 1231 extends from the inner end surface 122-A of the rod portion 122 to the interior of the rod portion 122. Along the circumferential direction of the inner wall 1231-A of the first channel 1231, a magnetic layer 1244 is provided on the inner wall 1231-A of the first channel 1231. The magnetic layer 1244 has an annular structure and is provided on the inner wall 1231-A of the first channel 1231. The magnetic layer 1244 consists of a south pole (S pole) 1244-1 and a north pole (N pole) 1244-2.

[0587] It should be understood that the magnetic sensor 513 here can be Figure 1 The magnetic sensor 130J shown is interchangeable.

[0588] Illustratively, the magnetic layer 1244 is formed by stacking an S pole 1244 - 1 and an N pole 1244 - 2 .

[0589] For example, the S pole and the N pole in the magnetic layer 1244 can be spaced apart and asymmetrically along the circumferential direction of the rod portion 122, as shown in FIG. Figure 67 The positional relationship between the S pole and the N pole is shown.

[0590] It should be noted that although Figure 64 The first channel 1231 of the rod portion 122 shown in the figure penetrates the rod portion 122 along the axial direction of the rod portion 122, that is, the first channel 1231 extends from the inner end surface 122-A of the rod portion 122 to the end of the rod portion 122 close to the head 121. However, it should be understood that the first channel 1231 of the rod portion 122 can extend from the inner end surface 122-A to any position of the rod portion 122, and the embodiment of the present application does not impose any limitation thereto. Figure 64 The structure shown is for schematic illustration only. Similarly, the magnetic layer 1244 may also extend to any position of the inner wall 1231-A of the first channel 1231, and this embodiment of the present application does not impose any limitation thereto. Figure 64 The structures shown are for illustrative purposes only.

[0591] In one example, the south pole 1244 - 1 is disposed between the inner wall 1231 -A of the first channel 1231 and the north pole 1244 - 2 .

[0592] In another example, the north pole 1244 - 2 is disposed between the inner wall 1231 -A of the first channel 1231 and the south pole 1244 - 1 .

[0593] In other embodiments, a plurality of magnetic layers 1244 may be provided on the inner wall 1231-A of the first channel 1231, the plurality of magnetic layers 1244 being spaced apart along the circumferential direction of the inner wall 1231-A of the first channel 1231, and the plurality of magnetic layers 1244 being asymmetrically provided. Figure 66 As shown, two magnetic layers 1244 are arranged on the inner wall 1231 -A of the first channel 1231 , and the two magnetic layers 1244 are arranged asymmetrically.

[0594] In other embodiments, reference Figure 67 A magnetic layer 1244 is also provided on the inner end surface 122-A of the rod portion 1122 of the input device 120. The magnetic layer 1244 is composed of an S pole 1244-1 and an N pole 1244-2. The S pole 1244-1 and the N pole 1244-2 are arranged at intervals along the circumferential direction of the rod portion 122 and the S pole 1244-1 and the N pole 1244-2 are asymmetric. The magnetic sensor 513 is arranged opposite to one end of the magnetic layer 1244.

[0595] In other embodiments, a plurality of magnetic layers 1244 (not shown) may also be provided on the inner end surface 122 -A of the rod portion 1122 of the input device 120 , and the plurality of magnetic layers 1244 may be asymmetrically arranged.

[0596] When the input device 120 is rotated, the direction of the magnetic field of the magnetic layer 1244 changes, causing the magnetic flux passing through the coil of the magnetic sensor 513 to change, generating an induced current in the magnetic sensor 513. When the input device 120 is stationary and the direction of the magnetic field of the magnetic layer 1244 does not change, no induced current is generated in the magnetic sensor 513. Therefore, when the input device 120 is rotated, the magnetic sensor 513 can detect the induced current generated by the magnetic layer 1244. The magnetic sensor 513 or a processor connected to the magnetic sensor 513 can determine the rotation state of the input device 120 and rotation information related to the rotation based on the change in the induced current, thereby identifying user input.

[0597] When the input device 120 is pressed, the magnetic flux of the magnetic field of the magnetic layer 1244 changes, generating an induced current in the magnetic sensor 513. When the input device 120 is stationary, the magnetic flux of the magnetic field of the magnetic layer 1244 does not change, and no induced current is generated in the magnetic sensor 513. Therefore, when the input device 120 is pressed, the magnetic sensor 513 can detect the induced current generated by the magnetic layer 1244. The magnetic sensor 513 or a processor connected to the magnetic sensor 513 can determine the movement state of the input device 120 and movement information related to the movement based on the change in the induced current, thereby identifying user input.

[0598] refer to Figure 68 and Figure 69 The sensing element may include N pressure sensors 514, which are arranged in the area near the outer end surface 121-A of the head 121. The N pressure sensors are arranged at intervals along the circumferential direction of the head 121. One pressure sensor 514 corresponds to one position, and N pressure sensors 514 correspond to N positions, where N is an integer greater than or equal to 2. It should be understood that the pressure sensor 514 here can be Figure 1 The pressure sensor 130B shown is interchangeable.

[0599] In one example, N pressure sensors 514 are disposed on the inner side of the outer end surface 121-A of the head 121 (eg, Figure 68 shown).

[0600] In another example, N pressure sensors 514 are disposed on the outside of the outer end surface 121 -A of the head (not shown in the figure).

[0601] When the input device 120 is rotated, the positions of the N pressure sensors change. The processor 110 can detect the differential components of the signals generated by the pressure sensors 514 at any adjacent positions, and pass these differential components through the charge amplifier and the filter circuit to analyze the rotation state of the input device 120 and the rotation information related to the rotation.

[0602] In one example, the processor 110 may respectively detect the differential components of the signals generated by the pressure sensors 514 located at the first and second positions, detect the differential components of the signals generated by the pressure sensors 514 located at the second and third positions, and so on, detect the differential components of the signals generated by the pressure sensors 514 located at the N-1th position and the Nth position, and analyze the differential components (referred to as first differential components) generated by the N pressure sensors 514 through a charge amplifier and a filter circuit to obtain rotation information of the input device 120 rotating along a first direction. The rotation direction of the first direction is the same as the distribution order of the pressure sensors 514 located at the first position to the Nth position; and the processor 110 Rotation information of the input device 120 in a second direction can be obtained by respectively detecting the differential components of the signals generated by the pressure sensors 514 located at the Nth and N-1th positions, detecting the differential components of the signals generated by the pressure sensors 514 located at the N-1th and N-2th positions, and detecting the differential components of the signals generated by the pressure sensors 514 located at the 2nd and 1st positions. The differential components generated by the N pressure sensors 514 (referred to as second differential components) are analyzed through a charge amplifier and a filter circuit to obtain rotation information of the input device 120 in a second direction. The second direction has a rotation direction opposite to the first direction and has the same rotation direction as the distribution order of the pressure sensors 514 from the Nth position to the 1st position. The processor 110 compares the calculated parameters of the rotation information in the first and second directions with the preset parameters for rotation in the first and second directions to determine the rotation information of the input device 120.

[0603] For example, if the input device 120 rotates in a first direction, then the parameters in the rotation information obtained from the first difference value satisfy the preset parameters for rotation in the first direction but do not satisfy the preset parameters for rotation in the second direction. Therefore, the processor 110 can determine that the input device 120 rotates in the first direction. Similarly, if the input device 120 rotates in a second direction, the parameters in the rotation information obtained from the second difference value satisfy the preset parameters for rotation in the second direction but do not satisfy the preset parameters for rotation in the first direction. Therefore, the processor 110 can determine that the input device 120 rotates in the second direction.

[0604] When the input device 120 is pressed, the input device 120 moves, and the signals detected by the N pressure sensors may not be exactly the same. There are differences in the signals detected by the N pressure sensors. Therefore, the processor 110 can detect the differential components of the signals generated by the pressure sensors 514 at any adjacent positions, and pass these differential components through the charge amplifier and the filtering circuit to analyze the movement status of the input device 120 and the movement information related to the movement.

[0605] In other embodiments, the sensing element may include N pressure sensors 514, which are disposed within the housing 180 and connected to a circuit board within the housing 180. A connector 200 is disposed within the input device 120, with one end of the connector 200 connected to the pressure sensors 514 and the other end attached to the outer end surface 121-A of the head 121 of the input device 120 (not shown). This allows pressure acting on the head 121 to be transmitted to the pressure sensors 514 via the connector 200, thereby identifying user input when the input device 120 is rotated or pressed. The method for determining the rotation of the input device 120 using the N pressure sensors 514 can be found in the above description and will not be repeated here.

[0606] In this embodiment, the connector 200 includes a first connector and a second connector that are rotatably connected. In one example, the first connector can rotate with the rotation of the input device 120 and is fixedly connected to the input device 120. The second connector does not rotate and is connected to the pressure sensor 514. When the input device 120 is rotated, the first connector can be driven to rotate, while the second connector does not move. The rotational connection between the first connector and the second connector can realize an electrical connection between the first connector and the second connector. In this way, while realizing the rotation of the input device 120, the pressure acting on the head 121 can also be transmitted to the pressure sensor 514 through the connector 200. For example, the connector 200 can be as follows: Figures 51 to 8 In the connector 200 shown, the first connector may be Figures 51 to 53 The first connecting member 210 is shown, and the second connecting member can be Figures 51 to 53 The second connector 220 shown, or the connector 200 may be as shown Figures 57 to 17 In the connector 200 shown, the first connector may be Figures 57 to 62 The first connecting member 210 is shown, and the second connecting member can be Figures 57 to 62 The second connecting member 220 is shown.

[0607] It should be noted that the wearable device 100 can be used, for example, Figures 46 to 69 When the embodiment shown realizes the function of recognizing the motion of the input device, it can also realize at least one of the following functions at the same time: Figures 4 to 45 The fingerprint recognition function of the wearable device 100 shown in FIG. Figures 70 to 93 The photographing function of the wearable device 100, for example, Figures 94 to 97 The PPG detection function of the wearable device 100, for example, Figures 98 to 99 The wearable device 100 has a function of improving the signal of the measured part, for example, Figures 102 to 103 The ECG detection function of the wearable device 100, for example, Figures 104 to 110The gas detection function of the wearable device 100, for example, Figures 111 to 118 The ambient light detection function of the wearable device 100, for example, Figures 119 to 123 The wearable device 100 has a body temperature detection function.

[0608] In one example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, the fingerprint sensor 130C may be provided in the head 121 or the rod 122 or the housing 180.

[0609] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, a camera 600 may be provided in the head 121 or the rod 122 or the housing 180. Optionally, a reflection device 710 may be provided in the head 121. Optionally, a channel may be provided in the input device 120. Optionally, a connector 200 may be provided in the rod 122.

[0610] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, the PPG sensor 130A may be provided in the head 121 or the stem 122 or the housing 180. Optionally, the input device 120 may further include a channel. Optionally, a connector 200 may further be provided in the stem 122. Figures 94 to 97 The various embodiments described implement PPG detection functionality.

[0611] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, a group of electrodes may be provided on the outer surface of the head 121 or the outer surface of the housing 180, as described below. Figures 102 to 103 The various embodiments described implement ECG detection functionality.

[0612] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, the infrared light transmitting unit 830 may be provided in the head 121 or the rod 122 or the housing 180. Optionally, the input device 120 may further be provided with a channel. Optionally, a connector 200 may further be provided in the rod 122. Figures 98 to 99 The various embodiments described achieve the function of improving the signal of the site to be measured.

[0613] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, the gas sensor 130I may be provided in the head 121 or the stem 122 or the housing 180. Optionally, the input device 120 may further include a channel. Optionally, a connector 200 may further be provided in the stem 122. Figures 104 to 110 The various embodiments described implement gas detection functionality.

[0614] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, the ambient light sensor 130F may be provided in the head 121 or the stem 122 or the housing 180. Optionally, the input device 120 may further include a channel. Optionally, a connector 200 may further be provided in the stem 122. Figures 111 to 118 Various embodiments are described that implement ambient light detection functionality.

[0615] In another example, in e.g. Figure 50 、 Figure 51 、 Figure 52 、 Figure 53 、 Figure 54 、 Figure 56 、 58 、 Figure 59 、 Figure 62 、 Figure 64 、 Figure 68 In the embodiment shown, a temperature sensor may be provided in the head 121 or the stem 122 or the housing 180. Optionally, the input device 120 may further include a channel. Optionally, a connector 200 may further be provided in the stem 122. Figures 119 to 123 The various embodiments described implement the body temperature detection function.

[0616] When the input device 120 implements user input, the wearable device 100 can output a feedback signal through the feedback device to provide the user with a better user experience, so that the user can determine whether the wearable device 100 successfully receives the user input.

[0617] In one example, the feedback device may include an element that uses force as a feedback signal. For example, the feedback device may include a motor that outputs force through vibration of the motor. That is, when the user operates the input device 120, the motor vibrates to give the user a vibration experience during the rotation process.

[0618] In another example, the feedback device may include an element that uses a sound signal as a feedback signal. For example, the feedback device may include a speaker that outputs the sound signal through the speaker. That is, when the user operates the input device 120, the speaker emits a sound signal to give the user a sound experience during the rotation process.

[0619] In another example, the feedback device may include an element that uses an electrical signal as a feedback signal. For example, the feedback device may include a metal electrode, and the electrical signal is output through the metal electrode. That is, when the user operates the input device 120, the metal electrode may output an electrical signal to give the user an electrical stimulation experience during the rotation process.

[0620] In another example, the feedback device may include an element that uses temperature as a feedback signal. For example, the feedback device may include a component with good thermal conductivity, through which a changing temperature is output. That is, when the user operates the input device 120, a changing temperature is output to give the user a temperature experience during the rotation process.

[0621] It should be understood that the feedback device may also include elements that output other types of feedback signals, and the above is only an exemplary illustration. It should also be understood that the feedback device may include one or more elements of the elements shown above and other elements not shown, and this application does not impose any limitation thereto.

[0622] In some embodiments, the feedback device is disposed in the input device 120 . In one example, the feedback device may be disposed in the head 121 of the input device 120 .

[0623] In this way, the space inside the shell occupied by the feedback device can be effectively saved; in addition, since the input device 120 can be in direct contact with the user, the feedback signal such as force or temperature output by the feedback device can be felt more directly by the user, greatly improving the user experience.

[0624] For example, when the input device 120 is rotated, the motor in the prior art is disposed inside the housing. Vibration of the motor within the housing causes the entire wearable device 100, including the input device 120, to vibrate, thereby providing tactile feedback to the user. In the embodiment of the present application, however, vibration of the motor within the input device 120 causes the input device 120 to vibrate, thereby providing tactile feedback to the user. Compared to the prior art, the vibration is stronger, and the user experiences tactile feedback from their fingers rather than vibration of the entire wearable device 100.

[0625] In other embodiments, the feedback device includes multiple components, some of which are arranged in the housing 180, and other components are arranged in the input device 120. The two components are used in combination to achieve more tactile feedback experience effects.

[0626] In one example, the feedback device includes multiple motors, some of which are located within the housing 180 and others within the input device 120. When the input device 120 is pressed, only the motors within the input device 120 vibrate, providing the user with a rotational tactile feedback. When the user makes a selection through the input device 120, the motors within the housing 180 vibrate, indicating confirmation.

[0627] In other embodiments, the feedback device may be disposed within the housing 180. Specifically, when the feedback device includes an element that uses force as a feedback signal, a connector 200 may be disposed within the input device 120, with one end of the connector 200 connected to the feedback device and the other end connected to the head 121 of the input device 120. When the feedback device outputs force through vibration, the vibration of the feedback device is transmitted to the head 121 of the input device 120 via the connector 200, thereby maximizing the tactile feedback experienced by the user's fingers rather than the vibration of the entire wearable device 100.

[0628] It should be understood that the connector 200 in this embodiment can be Figures 51 to 27 The only difference is that, in this embodiment, the other end of the connector 200 close to the head 121 is not connected to the fingerprint sensor 130C, but can be connected to the head 121.

[0629] In the above-mentioned multiple embodiments in which the wearable device 100 includes a feedback device, the processor 110 can control the feedback signal output by the feedback device according to the user input applied to the input device 120 by the user.

[0630] In some embodiments, the feedback device may include a motor.

[0631] In one example, assuming the user input is a rotation input, the processor 110 can control the motor to provide different vibration frequencies based on the rotation speed. For example, the faster the rotation speed, the faster the vibration frequency of the motor, and the slower the rotation speed, the lower the vibration frequency of the motor.

[0632] In another example, assuming the user input is a rotation input, the processor 110 controls the motor to provide different vibration intensities according to the magnitude of the rotation force. For example, the greater the rotation force, the greater the vibration intensity of the motor, and the smaller the rotation force, the smaller the vibration intensity of the motor.

[0633] In another example, assuming the user input is a movement input, which is achieved by the user pressing the input device 120, the processor 110 controls the motor to provide different vibration intensities based on the degree of pressure. For example, the harder the user presses the input device 120, the greater the vibration intensity of the motor, and the lighter the user presses the input device 120, the smaller the vibration intensity of the motor.

[0634] In other embodiments, the feedback device may include a speaker.

[0635] In one example, assuming the user input is a rotation input, the processor 110 can control the speaker to emit sounds of different rhythms according to the rotation speed. For example, the faster the rotation speed, the faster the rhythm of the sound emitted by the speaker, and the slower the rotation speed, the slower the rhythm of the sound emitted by the speaker.

[0636] In another example, assuming the user input is a rotation input, the processor 110 controls the speaker to emit sounds of different intensities according to the magnitude of the rotation force. For example, the greater the rotation force, the stronger the sound intensity of the speaker, and the weaker the rotation force, the weaker the sound intensity of the speaker.

[0637] In another example, assuming the user input is a movement input, which is achieved by the user pressing the input device 120, the processor 110 controls the speaker to emit sounds of different intensities based on the degree of pressing force. For example, the harder the user presses the input device 120, the louder the sound emitted by the speaker, and the softer the user presses the input device 120, the softer the sound emitted by the speaker.

[0638] It should be understood that Figures 46 to 69 The structures of the various components of the electronic device and the connection relationships between the components are only schematic illustrations. Any replaceable components that perform the same function as each component are within the scope of protection of the embodiments of this application. The relevant structures of each component will be described in detail below.

[0639] Above, combined Figures 46 to 69 , the structure of the wearable device identifying the rotation or movement of the input device in the embodiment of the present application is described.

In other embodiments, a portion of the camera may be disposed within the input device 120, and another portion of the camera may be disposed within the housing 180 of the wearable device 100. The two aforementioned embodiments are described below.

[0644] In the embodiment where the camera is provided on the input device 120, the camera may be provided on the head portion 121 of the input device 120 or on the stem portion 122 of the input device 120. Figures 70 to 74 In the embodiment shown, the camera is arranged on the head 121. Figures 75 to 77 In the embodiment shown, the camera is disposed on the rod portion 122. The structure of the camera will be described below with reference to the accompanying drawings.

[0645] In some embodiments, reference Figure 70 The main body 101 of the wearable device 100 includes a housing 180, a cover 114, an input device 120, and a camera 600. The cover 114 is connected to the top of the housing 180, forming the surface of the main body 101. In some embodiments, the cover 114 may be a display screen 140. The housing 180 is provided with a mounting hole 181. The input device 120 includes a head 121 and a rod 122. The head 121 extends outward from the housing 180, and the rod 122 is mounted in the mounting hole 181. A transparent cover 1211 is provided at the end of the head 121 away from the rod 122. A second channel 1232 is provided in the head 121, which is connected to the cover 1211. The camera 600 is disposed in the second channel 1232, and the camera 600 is oriented along the axial direction of the rod 122 toward the head 121. In this way, light can enter the camera 600 through the cover 1211 and the second channel 1232, thereby realizing the camera function.

[0646] After the camera 600 completes the photo shooting, it can transmit the image to the processor 110, and the processor 110 can present the image information to the user through an output device such as the display screen 140 of the wearable device 100. In order to realize the connection between the camera 600 and the processor 110, for example, continue to refer to Figure 70A connector 200 may be provided in the rod portion 122 , one end of the connector 200 is connected to the camera 600 , and the other end of the connector 200 is connected to the processor 110 (not shown in the figure) to achieve an electrical connection between the camera 600 and the processor 110 .

[0647] The input device 120 can be rotated around the axial direction of the rod 122, and the camera 600 is set in the head 121 of the input device 120. In the first example, the camera 600 can rotate with the rotation of the input device 120, and the connector 200 can be used as described above. Figures 6 to 19 In the second example, the input device 120 rotates and the camera 600 does not rotate, or the input device 120 and the camera 600 do not rotate, the connector 200 can adopt the above-mentioned Figures 21 to 23 The connector shown in FIG. 1 can be replaced with the fingerprint sensor 130C by the camera 600. In the embodiment where the camera 600 faces the cover 1211, the connection between the camera 600 and the connector 200 in the second example is more reliable.

[0648] Taking the second example as an example, refer to Figure 71The head portion 121 of the input device 120 is provided with a camera 600. A cover plate 1211 is provided at the end of the head portion 121 away from the rod portion 122. A gap is provided between the cover plate 1211 and the camera 600 (or, the cover plate 1211 and the camera 600 are in contact, which is not shown in the figure). Light is transmitted to the camera 600 through the cover plate 1211 and the gap. There is a gap between the camera 600 and the head portion 121 and they do not contact each other, so that when the input device 120 rotates, the camera 600 does not rotate. Exemplarily, a second channel 1232 is provided in the head portion 121. The second channel 1232 is connected to the cover plate 1211. The camera 600 is disposed in the second channel 1232. There is a gap between the camera 600 and the inner wall of the second channel 1232. There is also a gap between the camera 600 and the cover plate 1211. The connector 200 is internally sleeved within the rod 122 of the input device 120. A gap 120-1 exists between the fixing rod 260 of the connector 200 and the rod 122, preventing contact. This prevents the connector 200 from rotating when the input device 120 rotates. The end of the metal strip 270 of the connector 200, away from the camera 600, is electrically connected to the first circuit board 111. The first circuit board 191 is fixed to the housing 180 of the wearable device. In this way, the connector 200 can be fixed to the housing via the first circuit board 111. The end of the metal strip 270, closer to the camera 600, is electrically connected to the camera 600. Thus, the connector 200 can be electrically connected to the first circuit board 111, thereby achieving electrical connection between the camera 600 and the processor disposed on the first circuit board 111. When the input device 120 is rotated, the camera 600 and the connector 200 do not rotate with the rotation of the input device 120 because there is a gap between the camera 600 and the head 121 and they do not contact each other, and there is a gap between the connector 200 and the rod 122 and they do not contact each other.

[0649] In the embodiment of the present application, by disposing the camera 600 within the head portion 121 of the input device 120, the camera 600 can be effectively used to save space in the housing 180 while still being able to realize the photo-taking function. Furthermore, the camera 600 is oriented toward the head portion 121 along the axial direction of the rod portion 122, allowing for viewing from the outer end surface 121-A of the head portion 121, making the structure easy to implement and convenient to install.

[0650] In an embodiment in which the camera 600 is disposed on the head 121, the camera 600 may be directed toward the side 121-B of the head 121 (or toward one end in the circumferential direction of the head 121), and light may enter the camera 600 through the side 121-B to take pictures.

[0651] In some embodiments, reference Figure 72The input device 120 is provided with a connecting piece 720, and the connecting piece 720 includes a first part 721 arranged on the side of the head, and a camera 600 is arranged on the side of the first part 721 in the circumferential direction. The camera 600 faces the side 121-B of the head 121 along the radial direction of the head 121, and a transparent cover 1211 is arranged on the side 121-B of the head 121. In other words, the camera 600 faces the cover 1211, and the cover 1211 is an annular structure that surrounds the head 121 in the circumferential direction. Light can enter the camera 600 through the cover 1211 to take pictures.

[0652] Continue to refer Figure 72 The camera 600 includes a photosensitive element 610 and a lens 620. The photosensitive element 610 and the lens 620 are stacked and sleeved on the first portion 721 of the connector 720 in a direction (x-direction) parallel to the axial direction of the rod 122. In other words, the photosensitive element 610 is sleeved on the side surface of the first portion 721 in the circumferential direction to form an annular structure of the photosensitive element 610. The lens 620 is disposed between the cover plate 1211 and the photosensitive element 610. For example, the lens 620 is sleeved on the side surface of the photosensitive element 610 in the circumferential direction to form an annular structure of the lens 620. The lens 620 faces the cover plate 1211 to receive light entering from the cover plate 1211.
